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.
