Motorola Test Environments, HT 1000/JT 1000 Radios, NO. Description Function Beeps

with Option•Mate interface plug enabled through the HT 1000 RSS, TX and RX audio will be muted. Do not test Analog Voice Security (AVS) installed radios in the TEST MODE.

When the HT 1000/JT 1000 radio is operating in its normal environment, the radio's microcontroller controls the RF channel selection, transmitter key-up, and receiver muting. However, when the unit is on the bench for testing, alignment, or repair, it is removed from its normal environment. It cannot receive commands from its system and, therefore, the internal microcontroller will not key the transmitter nor unmute the receiver. This prevents the use of normal tune-up procedures. To solve this problem a special routine, called TEST MODE or “air test,” has been incorporated in the radio.

To enter test mode:

1.Turn the radio on.

2.Within ten seconds after the self test is complete, press the monitor button (side button 3, SB3) five times in succession. After the fifth press:

a.(HT 1000 radios), a tone is emitted to indicate that the rf test mode has been entered.

b.(JT 1000 radios), the display will show the firmware version of the microprocessor for two seconds, emit a tone, then display TEST MODE).

3.Each additional press of SB3 will advance to the next test channel. (refer to Table 6), and a corresponding set of tones will indicate the channel.

4.Pressing SB2 will scroll through and access test environments as shown in Table 5.

NOTE: Transmit into a load when keying a radio under test.

To exit test mode, turn the radio off then back on.
