3-2 5100 ES Models II/III Portable Radio Operating Manual March 2008
General Operation
Programming determines if the radio powers up on the last selected zone or the pre-
programmed home zone. Refer to Section 3.3 for information on the channel that is
selected. The minimum volume level may be set by programming. This can prevent
missed messages resulting from inadvertently turning the volume to an inaudible level.
3.1.2 Standard and Soft Power Down
To turn power off, rotate the ON-OFF/Volume control counterclockwise until a click
occurs. Power may remain on for an instant after turn-off occurs.
The soft power down feature prevents users from accidentally powering off the radio. A
soft power down feature can be programmed to prevent radio power from being turned off
by accidentally turning the on-off/volume control. Any side button can be programmed for
this function in addition to its normal function. To turn power off, press this button during
or after power is turned off in the normal manner (there is no time out).
The soft power down feature prevents users from accidentally powering off the radio. Any
side option button could be programmed to protect the power/volume knob. To power off
the radio, the side button had to be pressed during or just after the knob was turned to the
off position.
The enhanced soft power down feature adds a “standby” mode which mutes audio, turns
off lights, and can block a combination of buttons and switches.
Enhanced Soft Power Down has two modes of operation:
Normal Mode. If the power/volume knob is turned off nothing happens until the
programmed side button is pressed.
Standby Mode. When the power/volume knob is turned off,
the radio displays
“Standby”, audio is muted, and the indicator lights are turned off. The radio remains in
“standby” until the power knob is turned back on or the user presses a button that has
not been disabled.
Note No hardware is shut down during standby. This means that power savings while in
standby are negligible allowing the user to have immediate access to the system since they
do not have to power components back up.
The volume is set to half of maximum when the radio exits standby due to a button press or
switch change.
