General Operation
the channel it is indicating. For example, if the switch index is pointing to channel 3 and
channel 15 of the current zone is being displayed, rotating it to channel 4 selects
channel 4 of the current zone.
• If the rotary Channel Select switch is enabled, the radio always powers up on the
channel it is selecting.
If it is disabled, the radio can be programmed to power-up on the last selected or home
channel number of the last selected or home zone. With the “Last Zone”/“Home
Channel” configuration, the programmed home channel number of the last active zone
is selected. If it is not programmed, “Unprogrammd” is displayed. With earlier models,
the last selected channel is displayed when powering up on the last selected zone, and
channel 1 is displayed when powering up on the home zone.
3.3.4 Combined Zone and Channel
If the Combined Zone/Channel option is enabled, the flexibility to accommodate different
number of character combinations for Zone and Talkgroup is implemented. The
implementation for Combined Zone/Channel Display is as follows:
• Characters to Display Zone - (1-7)
• Space Between Zone / Talkgroup (optional)
• Characters to Display Talkgroup - This is a calculated field. (10 minus the number of
Zone Chars minus 1 (if Space) or 0 (if No Space).
The radios use the specified number of characters from the Zone and Talkgroup Alias
fields to create the combined display text. If the Zone or Talkgroup Alias is larger than the
number of characters specified, the radio truncates the alias to the specified number of
characters so that both the Zone and the Talkgroup fit into the display.
3.3.5 Dynamic Zone
The Dynamic Zone feature provides users the ability to setup “Favorite Channels” in one
dynamic zone, and allows the user to edit the channels without impacting any of the
channels already programmed to the Dynamic Zone.
A menu item in the 5100 ES allows the user to add channels to the favorite Zone. If The
Favorite Zone is enabled, the user has the ability to change the channels that are in his
favorites list, as follows:
1 Select the zone / channel to be placed into Favorites, using the zone/channel selectors.
2 Press the “Favorites” button or menu item for the 5100 ES (the radio remembers the
current zone/channel).
