require cables; it simply plugs into the right-hand side of the GPS Receiver
Module.
To help you keep track of battery life, the Power Module has a push button and 4
LED indicators to provide a quick indication of the percentage of battery time
remaining. Each light represents about 25% of battery life. Four green lights
indicate the battery is fully charged (100%). One red light indicates that there is
less than 25% of battery life left. To maintain the accuracy of the battery indicator
the Power Module must be calibrated periodically. To calibrate the Power Module,
see the Operation and Reference section, Chapter 2 - Equipment Description,
page 19.
External Power
For extended operation, an external power source is available as an option with
the Z-Max. The Z-Max GPS Receiver Module contains an external power
connector that allows you to power the receiver externally via an AC to DC
transformer or an additional battery. Optional cables are available to allow the use
of other DC power sources (10-28VDC) such as a vehicle battery or an auto
cigarette lighter port to power the receiver for extended periods.

Communication Module

Depending upon the options that you purchased, the Communication Module either
contains data links used in real-time survey applications or is an empty V-Module,
Figure 2.4. Operating the Z-Max during a post-process survey does not require data
links. The empty V-Module is needed to maintain a weather-tight seal of the Z-Max
