I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.
Being a user of older radios of many kinds, preferring them over more modern rigs, this manual was invaluable in the programming of my two. I now know for certain what the assorted buttons functions are, and am very grateful to have found this excellent site. Many thanks for your assistance, Tony.

Quick response and exactly what I was looking for and at a great fair price!
5 star quality on these downloadable manuals. Easy to read and all the information is there. A must when doing a custom install or needing to service your precious old school electronics.
4-4. Temperature Compensation Offset Adjustment
Save the temperature data at that time in the non-volatile memory as 25 ËC reference data. Note : 1. Usually, do not perform this adjustment. 2. Perform this adjustment in an ambient temperature of 22 ËC to 28 ËC. Perform it immediately after the power is turned on when the internal temperature of the unit is the same as the ambient temperature. 3. When D101 has been replaced, perform this adjustment after the temperature of this part has become the ambient temperature. Adjusting Method : 1. Rotate the AMS knob and display âTEMP ADJUSTâ. 2. Press the ENTER/YES button and select the âTEMP ADJUSTâ mode. 3. âTEMP = â and the current temperature data will be displayed. 4. To save the data, press the ENTER/YES button. When not saving the data, press the EDIT/NO button. 5. When the ENTER/YES button is pressed, âTEMP = SAVEâ will be displayed for some time, followed by âTEMP ADJUSTâ. When the EDIT/NO button is pressed, âTEMP ADJUSTâ will be displayed. Specifications : The âTEMP = â should be within âE0 - EFâ, âF0 - FFâ, â00 - 0Fâ, â10 - 1Fâ and â20 - 2Fâ.
4-5. Laser Power Adjustment
Laser power meter
Optical pick-up objective lens
BD board TP (I + 5V) TP (IOP)
Adjusting Method : 1. Set the laser power meter on the objective lens of the optical pickup. (When it cannot be set properly, press the 0 button or ) button and move the optical pick-up.) Connect the digital volt meter to TP (IOP) and TP (I+5V). 2. Rotate the AMS knob and display âLDPWRADJUSTâ. (Laser power : For adjustment) 3. Press the ENTER/YES button twice and display âLD $ 4B = 3.5 mWâ. 4. Adjust RV102 of the BD board so that the reading of the laser power meter becomes 3.4 +0.1 mW. â0 5. Press the ENTER/YES button and display âLD $ 96 = 7.0 mWâ. (Laser power:MO reading) 6. Check that the laser power meter and digital voltmeter readings satisfy the specified value. Specification :
Laser power meter reading : 7.0 Â± 0.3 mW Digital voltmeter reading : Optical pick-up displayed value Â± 10%
(Optical pick-up label)
210A 27X40 B0825
lop = 82.5 mA in this case lop (mA) = Digital voltmeter reading (mV)/ 1 (â¦)
7. Press the ENTER/YES button and display âLD $ 0F = 0.7 mWâ. (Laser power: MO reading) 8. Check that the laser power meter at this time satisfies the specified value. Specification :
Laser power meter reading : 0.70 Â± 0.1 mW
9. Press the EDIT/NO button and display âLDPWR ADJUSTâ, and stop laser emission. (The EDIT/NO button is effective at all times to stop the laser emission.)
