ProMARK X
If alkaline batteries are installed, they will have enough power to maintain the
unit’s memory for up to one month. If the Rechargeable Battery Pack is
installed, the amount of charge remaining will vary according to the age of
the battery pack.
External Power Operation
The ProMARK X can be operated from an external AC or DC power supply
with a Magellan adapter. Only Magellan equipment should be used to
connect the unit to any power source. All Magellan adapters and interfaces
have been designed to supply the correct level of DC voltage; the use of any
other equipment may harm the unit and will void the warranty.
As part of the power-on self-testing, the unit looks for an external power
source. If external power is available, the unit will bypass the batteries to use
external power. The batteries will not be recharged while external power is
in use.
The unit will not continue to draw on external power after it is turned off.
Batteries must therefore be installed in order to maintain the unit’s memory.
NOTE
External power bypasses the batteries. At no time are alkaline
or NiCad batteries recharged in the unit.
The unit can be operated from an AC power source when a Magellan adapter
is used. AC adapters are currently available for 110 VAC, 220 VAC, and 240
VAC. A reg12 VDC adapter is also available. Discuss your needs with
your Magellan dealer to be sure you purchase the correct adapter.
WARNING
Always be sure the unit is off when connecting or disconnect-
ing external power. Failure to observe this precaution may
result in memory loss or a frozen display.
