3-2 TRANSCEIVER PERFORMANCE TESTING
3.0 Test Mode
3.1 RF Test Mode
The RF Test Mode is a special routine that has been incorporated in the radio. This mode allows
bench testing of the radio at various test frequencies across the entire band, at both high and low
transmit power (if applicable), at various channel spacings, and with different coded or carrier squelch
types. Any customer specific programming in the radio will not be changed or affected by use of the
RF Test Mode.
To enter test mode:
1. Turn the radio on.
2. Within ten seconds after the self test is complete (self test tone is heard), press SB2
(Side Button 2 in Chapter 4, Figure 4-3) five times in succession. If the self test complete tone
is not heard, see Error Codes information in Chapter 5. Entry into the test mode is indicated
by a positive indicator tone followed by a good key chirp (GKC).
3. Upon entering test mode, the radio is on carrier squelch mode.
4. Press SB1 (Side Button 1) and scroll through and access test environments as shown in
Table 3-2.
5. Press SB2 and scroll through the channel spacing available as shown in Table 3-3.
6. Turn the channel selector knob to change the test channel for that environment as shown in
Table 3-4.
7. Press the PTT on a test channel to cause the radio to transmit at the test frequency for the
channel.
Note: “BKC” means Bad Key Chirp, “GKC” means Good Key Chirp
