4-2 PERFORMANCE TESTING
3.0 Test Mode
3.1 RF Test Mode
When the radio is operating in its normal environment, the radioÕs 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 Òair test,Ó has been incorporated in the radio.
To enter test mode:
■
■
Turn the radio on.
■
■
Within ten seconds after the self test is complete, press the side button 2, (SB2) Þve times in
succession.
■
■
After ÒCSQ XXÓ appears in the display, the radio is on channel XX, carrier squelch mode.
■
■
Pressing SB1 will scroll through and access test environments as shown in Table 4-2.
■
■
Pressing SB2 will scroll through the channel spacing available as shown in Table 4-3 and a
corresponding set of tones will be heard.
■
■
Pressing SB2 for 3 seconds will switch the radio to the Control Head Test mode. ÒLCDÓ
appears on the display.
■
■
Pressing SB1 will cause the radio to turn on all the segments of the Þrst character. Another
SB1 press will turn on all the segments of the next character and so on until the last character
(character 7).
■
■
Pressing SB1 at the end of the LCD test will activate the Icon Test. ÒICONÓ appears on the
display. The next SB1 press will turn on the Þrst icon.
■
■
Pressing SB1 at the end of the Icon test will activate the Button Test. ÒBUTTONÓ appears on
the display. Pressing any side button (except SB1) or any keypad button during the LCD test
of Icon test will immediately activate this test.
■
■
Pressing SB2 for 3 seconds in the Control Head Test mode will cause the radio to return to
the RF Test mode.
