3-4 ES Series Models II/III Portable Radio Operating Manual
General Operation
An enhanced password scheme allows up to four power-on (user) passwords, download
and upload passwords, and a master password to be programmed.
The current User password can be changed if the “Set User Password” option button or
menu parameter is programmed. Selecting this function displays prompts for entering and
confirming a new password. It is recommended that a number key not be used for this
function because the password mode is exited if that key is pressed to enter a number.
Refer to Section 10 for more information on passwords.
3.3 Zone and Channel Select
The selected zone and channel are selected and displayed as follows. For more information
on zones and channels, refer to Section 3.9.5.
3.3.1 Zone Select
The front panel Up/Down buttons briefly display the alias of the current zone. When not in
special modes such as the menu mode, pressing either the up or down button once displays
the alias of the current zone. Then quickly pressing it again changes the selected zone up
or down. The rotary A/B/C switch on the top panel can also be programmed for zone
select. The “A” position then selects Zone 1, “B” Zone 2, and “C” Zone 3 (if applicable).
After the highest programmed zone is displayed, wrap-around to the lowest programmed
zone occurs and vice versa. The selected zone is also displayed briefly on power up. If the
selected zone alias needs to be displayed continuously, it must be programmed as part of
the channel alias.
The Up/Down buttons on the front of the ES Series portable are typically used to scroll
through the various Zones that a user needs to access. To eliminate inadvertently
switching Zones if the radio is accidentally bumped and an Up/Down button is pressed, a
Zone Lock function is implemented. The Up/Down button will not scroll through zones
unless the Zone Lock button is first pressed. If the Zone Lock button is pressed, the Up/
Down buttons are available for scrolling. Upon five-ten seconds of inactivity, the Up/
Down buttons again are not usable for selecting a Zone. The Zone Lock function is
programmable for any programmable button on the radio.
