2.7.2 2-TONE PROGRAMMING

Program the transceiver for operation with a two- tone decoder as described in Section 4. Screens that need to be programmed with two-tone decoder infor- mation are as follows. Refer to on-line help for more information on parameters in these screens (press F1 with parameter selected).

Model Menu - “LMR” must be selected (see Section 4.4.6).

Screen Menu - Select “2Tone Code CH” and program the information in the screen (see Table 4-6).

Screen Menu - Select “Memory Channel” and pro- gram the information under “2Tone Dec” for each channel on which the decoder will be used (see Table 4-1).

Screen Menu - Select “Key & Display Assign” and program an option key or the microphone hanger for the monitor function so that the decoder can be re-activated when the call is complete (see Table 4-2).

2.7.3 5-TONE PROGRAMMING

Program the transceiver for operation with a five- tone module as described in Section 4. Screens that need to be programmed with five-tone decoder infor- mation are as follows. Refer to on-line help for infor- mation on parameters in these screens (press F1 with parameter selected).

Model Menu - “PMR” must be selected (see Section 4.4.6).

Select the following in the Screen Menu:

•“Rx Code CH” and program the information in the screen (see Section 4.5.2).

•“Tx Code CH” and program the information in the screen (see Section 4.5.2).

•“User Tone” and program the information in the screen (see Section 4.5.2).

•“Memory CH” and program the parameters in this screen that are related to 5-tone operation on the channel (see Figure 4-2).

NOTE: If performing the deviation adjustment in the next section, the long tone must be turned on in RPT/STN/ID on the Memory Channel screen.

•“Key & Display Assign” and program Tx Code and Call switches for use in transmitting 5-tone codes.

Setting 5-Tone Deviation

The only adjustment on the 2/5-tone module is a potentiometer for setting the transmit tone deviation for 5-tone operation. This control is factory preset and should not require readjustment in the field. However, if adjustment is required, proceed as follows:
