Test Mode and Error Codes: Test Mode
RF Test Mode
On entry into the RF test mode the radio hardware will be configured for the default carrier squelch
(CSQ) test mode environment. The test mode application will examine the following personality
parameters in the radio codeplug:
• Tx Channel Number.
• Rx Channel Number.
When the radio is in RF test mode the PTT button is used to key and dekey the transmitter.
Whenever the transmitter keys up, the test mode application illuminates the front panel red LED and
whenever the transmitter keys down the application extinguishes the front panel red LED.
Test Mode Environments
When the RF TEST menu is displayed, press the TM1 key to gain access to the RF test mode
environments:
• CSQ (Carrier Squelch) . . . (Default)
• TPL (Tone Private Line)
• DPL (Digital Private Line)
• TLS (Trunking Low Speed)
• THS (Trunking high speed)
• DTM (Dual Tone Modulation Frequency)
• M12 (MDC 1200)
When the appropriate environment is selected the test mode application will configure the radio
hardware for this environment.
Channel Numbers
When the cursor is blinking on the channel number field, TM2 will scroll through channels: 1,þ2,þ...n
(n is the highest channel number specified by the Tx/Rx pairs field). The test mode application will
examine the number of Tx/Rx pairs field contained in the personality area of the radio codeplug in
order to determine how many different channel number menu messages to display. Selecting one of
the channel numbers will reconfigure the radio hardware with the specific transmit/receive frequency.
The resulting frequencies will be as follows:
• Transmit frequency: Offset frequency + (Tx channel number #n * Channel step size).
• Receive frequency: Offset frequency + (Rx channel number #n * Channel step size).
The Rx/Tx channel number #n and Channel step size values are extracted from the personality area
of the radio codeplug and the offset frequency is derived from the offset frequency calculation
performed on entry into RF test mode.
CH Test Mode
On entry into the Control Head test mode, all front panel indicators and display segments are
displayed for a period of 2 seconds, and then extinguished.
When the radio is in Control Head test mode, all front panel momentary button presses/releases
(apart from the dedicated scroll and select keys and the volume control), static switch activations and
free revolving rotary activations are monitored. When any one of these is detected a short tone will
be heard and the associated button code (in decimal) and state will be displayed on the front panel.
