Battery Charger
The Battery Charger provides power to the 750M and charges the Battery only during 750M
operation. It also incorporates a Battery Test Circuit that allows the user to check the charge
on the Battery. Using the ‘BATTERY TEST’ Button and reading the five (5) multi-colored Battery
Status Indicators, a user can determine the state of the Battery, from ‘LOW’ to ‘100%’. To
determine true Battery power level, either disconnect the Power Adapter or place the Charger
switch in ‘OFF’, otherwise charging voltage will be displayed. Be cautious of leaving the Battery
in an automobile exposed to extreme heat or cold. In these situations take the 750M into a
home or office when not in use. Extreme temperature may cause the Battery to fail.
Battery charge time varies with age, initial battery power, and temperature and can take up to
12 hours from fully depleted to ‘100% charge. Operating the750M does not require the Battery
to be at 100%, but operating the750M with the Battery power level below ‘LOW’ may
prevent automatic backup of destination address and last location information.
To test the Battery simply locate and push the ‘BATTERY TEST’ Button which is recessed on the
bottom of the Battery Charger and read the corresponding Battery Status Indicator.
The Battery Charger has a switch with three selections:
In the ‘AUTO’ position, the charger will power the 750M, trickle charge the Battery,
and store addresses and last location information during shutdown.
BATTERY: In the ‘BATTERY’ position, no charging occurs. The ‘BATTERY’ position allows the
750M to be used in a stand-alone mode without the Power Adapter. If the 750M is
used in the ‘BATTERY’ position until the battery power is depleted, address book
and last location information may be lost.
In the ‘OFF’ position, the Battery is not charged when used with the Power Adapter
connected to the vehicle’s power accessory port, but will allow the750M to
operate. The ‘OFF’ position is used to shutdown the750M when in a stand-alone
mode, or to check Battery power with the Power Adapter connected and 750M in
Battery Operation / Stand-Alone Mode
The 750M Battery is a lightweight, 12 volt, sealed lead acid type that is pre-charged to be ready
for operation. Its sealed construction makes it leak resistant. The Battery has an optimum discharge time of 2 amp hours that should be sufficient to operate the 750M for up to one hour
if necessary.
Battery capacity degrades at low temperatures and over the life of the system.
In the event that the vehicle power port is unusable, such as a blown fuse, or if required for
an airport security check, the 750M can be used solely from a new, fully charged Battery for
periods up to 1 hour. To do so, simply slide the Battery Charger switch to ‘BATTERY’. Be
certain to slide the Battery Charger switch back to ‘OFF’ or ‘AUTO’ when finished to avoid
depleting the Battery.
Map Area Switching
The 750M incorporates a feature called ‘Auto Map Switching’. When the 750M is transported
from one Map Area to another, it will automatically sense the change and then switch to the
correct Map Area within several minutes if other Map Areas have been purchased and
unlocked. In the event that the 750M needs to be manually switched to a different Map Area, it
can be easily done as follows:
Step 1: Refer to Map Area illustration on page 27.
Step 2: Press OPTION to arrive at the ‘User Options’ screen.
