Chapter 4 Test Mode and Error Codes

Test Mode

General

The test mode allows the technician to monitor a set of radio parameters, to configure the radio
hardware in a number of predefined ways, and have access to a number of test procedures. Two
basic areas of functionality are provided by the Test Mode:
• RF test mode - allows the RF functionality of the radio to be tested.
• CH (Control Head) test mode - allows the radio display, buttons and switches to be tested.
The purpose of the test mode is to test the radio unit and its interfaces, but not to test the various
accessories. However, the mobile radio is incapable of operating in isolation without a minimum set
of accessories. The following accessories are assumed:
• Microphone
• External speaker (only models II and III)
• Control head model I, II or III
If an accessory is subsequently connected to the radio after the test mode application has already
been invoked, the radio will ignore any resulting power up messages received on the serial bus.

Test Mode Features

On entering Test Mode the radio will be in an idle state, all indicators are extinguished and the RF
TEST Mode Select menu message will be displayed.
Test mode control is provided by a set of menus which may be scrolled through and selected. The
dedicated buttons TM1 (Select) and TM2 (Scroll) (see Figure 4-1 on page 2) are used to navigate
through these menus.
