Table 4-2 Key and Display Assign Screen Description (Continued)

Parameter	Key		Description
	Label
RF ATT	ATT	Toggles the receive attenuate function on and off (see Section 3.5.13).
Lock	LOCK	Locks/unlocks all programmable keys except CALL, MONI, and EMER to prevent them from being
		accidentally pressed (see Section 3.5.9).
Beep	BEEP	Toggles the key beep function on and off (see Section 3.3.10).
Light	LITE	Turns the LCD backlight on and off (see Section 3.3.9).
Bank Up		Selects the other bank of sixteen channels if applicable.
High	HIGH	Changes the power output for the current channel to the level programmed of the key. Pressing the key
Low 1	LOW1	again reselects the preprogrammed power level for the channel. The change may be temporary or per-
Low 2	LOW2	manent for that channel depending on the programming of the “RF PWR Selection” parameter later in
		this screen (see description which follows).
C. Tone	TONE	(Continuous Tone Memory Channel) This key selects the continuous tone mode which allows the Call
CH Ent		Guard (CTCSS) tone to be selected from the front panel (see Section 3.5.5). These tones are pro-
		grammed by the Continuous Tone screen described in Table 4-4.
Talk	TA	Toggles the talk-around mode on and off (see Section 3.5.16).
Around
Wide/	W/N	Temporarily toggles between the wide and narrow band modes (see Section 3.5.19). When the channel
Narrow		is changed or power is cycled, the wide/narrow mode programmed for the channel frequency specified
		in the memory Channel screen is again selected.
DTMF	DTMF	Pressing this key enables the DTMF autodial mode. After pressing this key, the number to be dialed is
Autodial		selected by the up/down	keys. Then press and hold this key to transmit the number (see Sec-
		tion 3.5.7). The available DTMF numbers are programmed by the DTMF Autodial screen described in
		Table 4-3.
Emergency	EMER	Pressing this key transmits an emergency call. If “Single” is programmed, it is transmitted only once; if
Single		“Repeat” is programmed, it is transmitted repeatedly with LMR models, or until the proper 5-tone code
Repeat		is received with PMR models. The emergency channel is specified by the CH Atr parameter on the
		Memory Channel screen described in Table 4-1. A DTMF code is transmitted if it is entered on the
		“Emergency” line of the DTMF Autodial screen (see Table 4-3). Additional emergency parameters are
		programmed in the Expert screen described in Table 4-8.
OPTx Out	OPT1	A “OPT1-OPT3 Out” key switches the respective pin of the 30-pin option connector high or low (this
	OPT2	connector is located inside the transceiver, and is used, for example, by the optional 2/5-tone module).
OPTx	OPT3	A “OPT1-OPT3 Momentary Out” key produces a high or low pulse on the respective pin of this 30-pin
Mom Out		connector.
Call	CALL	When equipped with the optional 2/5-tone module, transmits the 2-tone or 5-tone code.
Call A/B	CALL	PMR mode w/5-tone option only. Transmits code using channel 30 (A) or 29 (B).
Tx Code/	TX CH	PMR mode w/5-tone option only. Selects transmit 5-tone code.
CH Up/Dn
ID MR	ID MR	PMR mode w/5-tone option only. Recalls and erases stored codes that have been received
Select
Trunking	GRP	This switch is for a SmarTrunk function, so it is not available with this transceiver.

		OTHER MENU PARAMETERS
Hanger	Any or none of the following hanger functions can be programmed:
Action	Monitor - Disables CTCSS/DCTS Call Guard signaling on off-hook and re-enables it when back on-hook.
	Scan - Automatically enables scanning when placed on-hook.
	Prio A - Automatically selects the priority A channel when taken off-hook.
Beep On/	Enables or disables the key press beep. This programming can be overridden by the power-on menu (see Section
Off	3.3.4) or BEEP key (see Section 3.3.10).
