Transceiver Performance Testing Test Mode 3-7
3.3 Test Mode
3.3.1 Entering Test Mode
1. Turn the radio on.
2. Within 10 seconds after “Self Test” is complete, press Side Button 2 five times in
succession.
3. The radio beeps.
3.3.2 RF Test Mode
When the radio is operating in its normal environment, the radio's microcontroller controls the RF
channel selection, transmitter key-up, and receiver muting, according to the customer codeplug
configuration. However, when the unit is on the bench for testing, alignment, or repair, it must be
removed from its normal environment via a special routine, called TEST MODE or “air test”.
1. Each short press of Side Button 2 changes the test environment (CSQ->TPL->DIG->USQ
->CSQ). The radio beeps once when radio toggles to CSQ, beeps twice for TPL, beeps three
times for DIG and beeps four times for USQ.
2. Each short press of Side Button 1 toggles the channel spacing between 20 kHz/25 kHz*,
12.5 kHz and 20 KHz. The radio beeps once when radio toggles to 20KHz, beeps twice for 25
kHz* and beeps three times for 12.5 kHz.
3. Turning of the Channel Knob changes the test channel from 1 to 16 as described in
Table 3-3. The radio beeps in each position.
3.3.3 LED Test Mode
1. Press and hold Side Button 1 in RF Test Mode. The radio beeps once.
2. Upon any button/key press, the radio lights up the red LED.
3. Consequently, upon any button/key press, the red LED is turned off and the radio turns on the
green LED.
4. Consequently, upon any button/key press, the green LED is turned off the radio shall turn on
both LEDs.
3.3.4 Speaker Tone Test Mode
1. Press and hold Side Button 1 after LED Test Mode. The radio beeps once.
2. The radio generates a 1 kHz tone with the internal speaker.
NOTE
DIG is digital mode and other test environments are analog mode as described in Table 3-2.
