Fully functional usable service manual. Considering the age of the manual and device quality was better than expected
 ;
Thank you very much, I've been very happy to find this manual on "Owner Manual". It's a perfect copy and it has been really useful for my work!
;
It took about 24-hours after my payment before I was able to get to the download. Apparently, payment processing is not 100% automated. That is no big deal, just be aware of that going in.
After I got to it, it was in good shape, easy to read, etc. Not some cheap FAX copy looking thing.
Also, this site was the cheapest I found. Another Plus!
;
Good price, very legible manual, exactly what I needed -- but had to wait a day to actually get the download of the manual. Would have preferred to download it immediately after payment rather than waiting for someone to "process" my order. I was surprised that I had to wait that long.
;
As the only source for this manual it rather rank quite high since it is well scanned and perfectly readable.

Check the RF Unit
Finding out the Defective Unit
Prepare HS Test Fixture and BU Test Fixture. Place the HS Test Fixture on the cradle of the base unit for checking, then confirm that they are linked. Place the handset for checking on the cradle of the BU Test Fixture, then confirm that they are linked. How to confirm the link is as follows; press the TALK button and confirm Handset in use is displayed on BU LCD.
6.4.2.
Handset Test Fixture for Base Unit
Test Fixture has two modes. 1. TEST mode: (RF Power Low mode) The switch of Test Fixture changed with TEST mode side. Then Test Fixture is in TEST mode. 2. Normal mode: (RF Power Normal mode) The switch of Test Fixture changed with Normal mode side. Then Test Fixture is in Normal mode. NOTE: Audio is coming from Receiver whether switch is TEST mode or Normal mode. This test simulates the handset is at very large distance from the base unit and the TX signal from handset to base is very small. Procedure: First place handset Test Fixture on base under test to charge (exchange security code); then remove handset from base after you hear a beep; then press TALK to operate. The LCD will show TALK. This means that the base unit sensitivity is OK. If a beep is not heard, Replace the RF unit. NOTE: 1) Only KX-TG2583C/2563C/2553C/2503C with marks HS Test Fixture can be used for troubleshooting. Regular KXTG2583C/2563C/2553C/2503C production samples do not have the switches needed for troubleshooting.
