Last week I bought a second hand Panasonic AG-7500 SVHS Hi-Fi Video Cassette Recorder. It is a professional machine with many video and audio options. I feared it would be a huge quest to find a manual. I was delighted when I found owner-manuals.com. After payment I received the file to download the next day already. The quality is great. I am very happy. Thanks!
The owner's manual/operating instructions that I purchased was the original factory document and it was in at least three and maybe more languages. I no longer have it because I sold the tape recorder and included the owner's manual/operating instructions and a service/repair manual that I bought on ebay for the new owner.
This manual is very useful. Because pioneer sx-q180 is unhandy to use without manual.
Manual was destroyed and this purchase made it possible to recover my manual . It was easy to down load and smooth to use thanks .
Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
â¢ Each mark on the graphic indicator indicates the relative change between the latest barometric reading and the one before it.
A built-in altimeter uses a pressure sensor to detect the current air pressure, which is then used to estimate the current altitude. The watch is pre-programmed with ISA (International Standard Atmosphere) preset values, which are used to convert air pressure readings to altitude values. If you preset a reference altitude, the watch will also calculate the current relative altitude based on your preset value. Important! â¢ This watch estimates altitude based on air pressure. This means that altitude readings for the same location may vary if air pressure changes. â¢ Do not rely upon this watch for altitude measurements or perform button operations while engaging in sports where there are sudden altitude changes, while sky diving, hang gliding, or paragliding, or while riding a gyrocopter, glider, or any other aircraft. â¢ Note that the following conditions will prevent you from obtaining accurate readings: When air pressure changes because of changes in the weather Extreme temperature changes When the watch itself is subjected to strong impact â¢ In order to avoid measurement problems caused by differences in the watchâs temperature, be sure to wear the watch so that it comes into direct contact with your skin. â¢ Do not use this watch for measuring altitude in applications that demand professional or industrial level precision.

â¢ The examples on the left indicate that the latest reading is less than the previous one, while those on the right indicate the latest reading is greater. Barometric Pressure Graph Barometric pressure indicates changes in the atmosphere. By monitoring these changes you can predict the weather with reasonable accuracy. The following shows how to interpret the data that appears on the barometric pressure graph. A rising graph generally means improving weather.
A falling graph generally means deteriorating weather.
Note that if there are sudden changes in weather or temperature, the graph line of past measurements may run off the top or bottom of the display. The entire graph will become visible once barometric conditions stabilize. If any of the conditions listed below is present during one of the regular 3-hour measurements, a blank is inserted into the graph in place of a mark. The next time a successful reading is obtained (during a regularly scheduled 3-hour measurement), the current reading is compared with the last successful reading and the corresponding mark is added to the graph. â¢ Sensor data error (ERROR flashing on the display) â¢ Low battery power (BATT flashing on the display) â¢ Reading outside of measurement range (FULL on the display)
How the Altimeter Works
The watch measures relative altitudes in relation to a reference altitude set by you. You can set a reference altitude using zero reset, or by specifying an altitude value from a map, sign post, etc. â¢ After you set the reference altitude, the watch adjusts its air pressure to altitude conversion calculation accordingly. Setting a Reference Altitude Value With this method, you can specify a current altitude value you obtain from a map or signpost. Then the watch measures altitude relative to the value you set. â¢ When mountain climbing, you can set the reference value in accordance with a marker along the way or altitude information from a map. â¢ The altitude measurements produced by this watch are subject to error caused by changes in air pressure. Because of this, we recommend that you update the reference altitude whenever one is available during your climb.
Barometer Mode Screen
A measurement cycle starts after you enter the Barometer Mode, with readings being taken every three seconds for the first four or five minutes. After that, readings are taken every minute. Measurements you take in the Barometer Mode do not affect the barometric pressure information that appears on the Timekeeping Mode Screens. This means you can use the Timekeeping Mode Screen to see trends over a longer span, and the Barometer Mode to find out barometric pressure changes over a shorter term.
To start a barometric pressure measurement cycle Press C to enter the Barometer Mode. After a few Graphic indicator seconds, the result of the current barometric pressure reading appears on the display. â¢ Barometric pressure is displayed in units of 1hPa/mb (or 0.05inHg). â¢ The mode indicator flashes while a measurement operation is in progress. â¢ While a barometric pressure measurement operation is in progress in the Barometer Mode, press D to stop the Barometric pressure current operation and restart a new measurement cycle.
Mode indicator Timekeeping Mode time
To set a reference altitude value 1. Press C to enter the Altimeter Mode, and wait for a few seconds until the current altitude value appears on the display. 2. Hold down A until the current altitude value starts to flash. This indicates the reference altitude setting screen. 3. Use D (+) and B (â) to change the displayed value in 5-meter (20-foot) increments. â¢ You can set a reference altitude value in the range of 0 to 4000 meters (0 to 13120 feet). 4. Press A to exit the setting screen. â¢ After you press A, the numbers on the display indicate that the watch is making internal adjustments. This operation takes about nine seconds. Once adjustments are finished, the altitude display appears. Reference Altitude Zero Reset With zero reset, you can set the reference altitude to zero. The watch then measures altitude relative to zero. â¢ To determine the height of a tall building, set the reference altitude to 0 on the ground floor. Note, however, that you may not be able to get a good reading if the building is pressurized or air-conditioned. â¢ Before beginning a climb up a mountain, you could set the reference altitude to 0m at the foot of the mountain. This makes it possible to determine the difference in altitude between the reference point and your destination. To zero reset the reference altitude 1. Press C to enter the Altimeter Mode, and wait for a few seconds until the current altitude value appears on the display. 2. Hold down A until the current altitude value starts to flash. This indicates the reference altitude setting screen. 3. Press B and D at the same time to change the displayed value to zero. 4. Press A to exit the setting screen. â¢ After you press A, the numbers on the display indicate that the watch is making internal adjustments. This operation takes about nine seconds. Once adjustments are finished, the altitude display appears.
â¢ Some countries express barometric pressure in units of millibars (mb) instead of hecto-pascal (hPa). It really makes no difference, because 1hPa = 1mb. In this manual, we use hPa/mb or hPa (mb). â¢ You can change the measured barometric pressure unit between hecto-pascals/ millibars (hPa/mb) and inchesHg (inHg). See âTo specify the barometric pressure unitâ for details. â¢ The message FULL appears on the display whenever the barometric pressure reading is outside the measurable range of 600hPa/mb to 1100hPa/mb (17.70inHg to 32.45inHg). The barometric pressure value reappears when the barometric pressure reading returns to the measurable range. Barometer Mode Graphic Indicator In the Barometer Mode, the graphic indicator shows the Graphic indicator current barometric pressure. Segments are darkened in (Indicates 1018hPa/mb) the graphic indicator from the left (lower pressure) to the right (higher pressure). â¢ In the range of 600 to 950hPa/mb each rise of 35hPa/ mb causes one more segment to be darkened. In the range of 951 to 1045hPa/mb, each rise of 5hPa/mb causes one more segment to be darkened. All segments are darkened when the barometric pressure is 1046hPa/ mb or greater. â¢ When the barometric pressure unit is set to inHg, the watch actually measures in hPa/mb units and then converts to inHg. Because of this, the graphic indicator will show the hPa/mb value before switching to the corresponding inHg value.
Using the Altimeter Mode
A measurement cycle starts after you enter the Altimeter Mode, with readings being taken every three seconds for the first four or five minutes. After that, readings are taken every minute.
Graphic indicator (Indicates 1550m)
â¢ Altitude is displayed in 5-meter (20-foot) units. â¢ The mode indicator flashes while a measurement operation is in progress. â¢ While an altitude measurement operation is in progress in the Altimeter Mode, press D to stop the current operation and restart a new measurement cycle. â¢ The measured altitude may be a negative value in cases where there is a reference altitude value set or because of certain atmospheric conditions.
Altitude â¢ You can change the unit of measurement for the Timekeeping displayed altitude values between meters (M) and feet Mode time (F). See âTo specify the altitude unitâ.
â¢ The message FULL appears whenever the altitude reading is outside the display range of â4000 to +4000 meters (â13120 to +13120 feet). The altitude value reappears when the altitude reading returns to the measurable range. â¢ In the Altimeter Mode, the graphic indicator shows the current altitude. Segments are darkened in the graphic indicator from the left (lower altitude) to the right (higher altitude). In the range of 5 to 1000 meters (20 to 4000 feet), each increase of 45 meters (180 feet) causes one more segment to be darkened. In the range of 1005 to 2800 meters (4020 to 9400 feet), each increase of 195 meters (580 feet) causes one more segment to be darkened. All segments are darkened when the altitude is 2805 meters (9420 feet) or greater.
