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.

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 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 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 BIOS as “activity”. As a result, the

MX1’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.

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)

Custom Setting

CPU Custom Setting is user configurable in 1 second increments up to 63 seconds. After selecting

Custom, press the down arrow to move the highlight to the seconds setting. Use the numeric keys

to enter number of seconds. Higher second values will adversely affect battery life.
