Line 1 shows the currently selected item name (XXXXXXXX) from the list. Line 2 indicates the list 
(YYY) that the selection is to be made from and the number of the selected item (ZZZ) within the list. (In 
some cases the information on lines 1 and 2 will be exchanged.) Enter the system selection mode by 
pressing the SYS key. If SYSTEM 2 is the current selection, the display appears as follows: 

S O U T H 

S Y S    =      2 

Line 1 contains the current system name, SOUTH; and line 2, SYS = 2, indicates that selection is from 
the system list and it is the second system within the list. 

A new system from the list is selected by using the 

 ramp control or by directly entering the system 

number with the numeric keys. The 

 ramp control scrolls through the list in increasing and 

decreasing order. In the previous example, pressing up with the 

 ramp control selects the EAST 

system as shown in the next display.  

E A S T 

S Y S    =      3

 

The radio can be programmed to wrap around from one end of a list to the other end or to stop at the ends. 

To directly access a selection, enter the corresponding number (e.g. 4) followed by MENU to activate the 
selection. The entered number is displayed on line 2 as shown below. Line 1 shows the current list being 
used for selection. 

S E L   S Y S

If a mistake is made while entering the number, press the DEL button to backspace once and correct the 
entry. If an invalid number is entered, a short low-pitched tone sounds when MENU is pressed. 

To exit the selection mode, press the CLR button or wait for the time-out. If the selection mode is cleared 
while an entry is pending (i.e., numbers are entered on line 2, but MENU has not been pressed), the entry 
on line 2 will be disregarded and the previous selection will remain active. If the time-out activates while 
an entry is pending, the entry on line 2 will be selected if it is within the valid range; if it is out of range, 
the entry on line 2 will be disregarded and the previous selection will remain active. 

 

While in system, group or channel selection mode, the radio continues to receive calls 
normally and continues scanning, if it is enabled. If a call is received during the 
selection mode process the radio will return to the normal receive mode display. 
Continuing with the selection process will return the display to the same point in the 
selection process if the selection mode time out has not yet expired. Any press of the 
PTT button during the selection mode process will initiate transmission and exit the 
selection mode. 

Feature Encryption Display is available through the menu function and, if programmed, appears in the 
menu as “FEATURES.” This data indicates current features programmed into the radio as well as 
information required to add features to the radio.
