Part No. 001-7600-001
Ch Atr
(Channel
Attribute)
Press (Enter) to display the menu which selects one of the following choices:
A: Priority A - The channel is selected when the Prio A key is pressed, and it is monitored during priority scan.
In addition, the microphone hanger can be programmed so that this channel is automatically selected when-
ever an off-hook condition occurs (see Table 4-2).
B: Priority B - The channel is quick selected when the Prio B key is pressed. It is not monitored during priority
scan.
E: Emergency Channel - Transmission occurs on the channel when the Emergency switch is pressed.
Emergency Off - Deletes the emergency designation on current channel if applicable. If no emergency channel
is designated, transmission occurs on the currently selected channel.
SmarTrunk II™ On/Off - Toggles the SmarTrunk function on and off on the bank. This function is not
available with this transceiver.
Channel Insert - Inserts a blank channel by pushing the other channel information down one line.
Channel Delete - Deletes the programming information on the current line and moves the channel information
below it up one line.
Return - Exits the menu and returns to the main screen.
Frequency
(Rx/Tx)
Enter the desired frequency for the channel. Enter a frequency within the frequency range of the transceiver:
VHF = 136-155 or 146-174 MHz, UHF = 400-430, 450-470, 470-490, or 488-512 MHz. Channel steps in mul-
tiples of 5.0, 6.25, or 7.5 kHz only. If no receive frequency is entered, no other data can be programmed on the
line. Other special functions associated with frequency are as follows:
Rx Freq - Press the backspace key to toggle between wide and narrowband. Narrowband is indicated by “n” to
the right of the frequency. Press the spacebar to toggle receive inhibit on and off indicated by “i” to the left
of the frequency. This limits the channel to priority or emergency use only (it is not available as a regular
channel).
Tx Freq - To enter the same frequency as the receive frequency, enter nothing or “=”. The “
←
” symbol means
same as receive frequency. Enter a space to disable transmitting on the channel (“Inhibit” is then displayed).
F8 and F9 can be used to cut and paste frequencies. Press (Enter) when the desired frequency has been
entered.
CTCSS/
DTCS
(Rx/Tx)
Enters the receive and transmit tone (CTCSS) Call Guard® frequency or digital (DTCS) Call Guard code. Press
(Enter) to display the tone selection table. Select a tone by scrolling to it and pressing (Enter). Press the space-
bar or backspace key to increase or decrease the entered frequency. The “
←
” symbol means same as receive
code.
The length of the CTCSS reverse burst can be set by the “CTCSS Reverse Burst” parameter on the Common
Screen (see Table 4-7). A non-standard CTCSS tone from 60.1 to 300.1 Hz can be specified on the Expert
screen and then selected by “USER”. If a CTCSS tone is selected by the TONE option switch, it overrides the
channel programming until “TON--M” is reselected.
Digital codes must always be entered directly (there is no table) and tone frequencies can be entered directly. Be
sure to enter the tone decimal point or the number is interpreted as a digital code. To toggle the polarity of digi-
tal codes, press the spacebar or backspace key. The N or I indicates Normal or Inverted polarity. In
addition, the polarity of digital Call Guard signaling for all channels is set on the Expert screen.
Text Programs the 7-character alpha tag that is displayed when a channel is selected. If no text is programmed, the
channel number is displayed as CH-xx. Allowable characters are A-Z (upper or lower case), 0-9, ’ * , + $ ’ ( ) –
/ < = > ? @ [ \ ] _ { | } ~. However, some characters, especially lower case letters, may be difficult to see. The tx
up arrow is displayed by “:” , and the rx down arrow by “;”. Special characters may be programmed in the
Expert screen (see Table 4-8) and used for the positions 3-7 only (positions 1 and 2 can display only regular
characters). To enter a special character, press PgUp/PgDn to scroll through and select characters A-P.
TOT
(Time-Out
Timer)
Disables the transmitter on that channel if it is keyed continuously for longer than the programmed time. The
times for this timer and other related functions are programmed in the Common Screen (see Table 4-7).
