The ‘test’ facility enables T2000 trunked radios to emulate a multichannel radio, using
the frequencies reserved for trunking.
For a description of how to put the radio in test mode, refer to Section 5.8, “Trunked
Radios: Test Mode”. Once the radio is in test mode, functional testing can be carried out
as described in Section 4.4 and Section 4.5.
 When in test mode, connect the antenna socket to a dummy load to pre-
vent interference with trunking systems. Avoid testing on channels in use
locally.

Connect the radio to an antenna and switch on.
Check that the radio locks onto the system:
T203X radios: the  LED illuminates.
T2040 radios: the  annunciator will appear in the control head display.
The following parameters relating to the local trunking system base station must
be correctly programmed before the mobile will lock onto the system:
• Base station channel numbers and frequencies.
•Network ID.
• Zone and area field length.
• Base station control channel number in the hunt list.
• Valid acquisition authorisation code (for test purposes this can be set to ‘none’,
which allows total access).
Initiate a call to a known unit identity. For test purposes this can be your own
identity.
Check that:
• The radio beeps.
• A 0.5s ringing tone is sounded.
• The receiver unmutes.
• T203X: The  LED illuminates.
• T2040: the  annunciator comes on.
