Power Management
When changes have been made, press an arrow key to go to another parameter or menu or press
ESC to go to the Exit Menu.
Keep in mind the MX1-IS does NOT have a backup battery .
Power Mgt
This parameter must be set to On before timer options can be activated. When Power Management
is Off, the CPU setting is Full Speed.
Note: Critical Suspend. The Off Timer is ignored when Power Management is disabled -- the
MX1-IS will skip critical suspend mode (running on backup battery) and turn off
immediately. It will not use any backup battery power and currently unsaved information
will be lost.
Values: On, Off
Default: On
CPU and Suspend Timers and RF Communication
When using an MX1-IS with a 2.4GHz radio driver (see previous section titled “\PCTCP Files”),
the CPU and Suspend timers can be affected by the radio.
The 2.4 radio has a time-out setting. This time-out setting is in the PROTOCOL.INI file under
inactivity time. This time, by default, is 5 seconds and is the lowest possible value. During this 5
seconds, the radio is polled which is detected by the MX1-IS BIOS as “activity.” As a result, the
MX1-IS's Power Management keeps resetting the CPU and Suspend timers.
CPU
Note: Pwr Mgt Modes - Power Mgt must be set to On before the value in CPU has any effect
on the MX1-IS.
The CPU setting determines how Power Management values control the CPU.
Aggressive setting maximizes battery life.
Moderate will balance battery life and performance.
Light will maximize performance.
Full Speed disables power management of the CPU only.
Custom setting is used to set the CPU timer in 1 second increments.
Values: Aggressive (1 second)
Moderate (5 seconds)
Light (15 seconds)
Full Speed
Custom (user configurable in 1 second increments;
range = 1 - 63 seconds)
Default: Aggressive (1 second)
