DMP 310  (260-2876)              Power Options         Faxback Doc. # 4703

You can use the supplied, factory-installed AC power pack to power the
printer from a standard AC outlet. For portable operation, you can remove
the AC power pack and use battery power. Battery power requires a battery
holder, two nickel-cadmium batteries, and a battery charger. These are not
supplied.

USING AC POWER

The AC power pack is installed at the factory. If you remove and re-install
the AC power pack, be sure it clicks into place.

CAUTIONS:

* Never install or remove the AC power pack while it is plugged in.

* Before you plug in the AC power cord, be sure POWER is set to O (off) and
  the printer is not connected to the computer.

* Plug the power cord into a 110-volt, properly grounded, AC outlet or 
  approved power strip, such as Radio Shack's Plug-In Power Strip (26-1396)
  or Power Switching System (26-203). Check your computer's owner's manual
  for information about the use of a power strip.

USING BATTERY POWER

For portable operation, you can power the printer from two nickel-cadmium
batteries (23-230). You must install the batteries in a custom battery
holder (26-2877).

Before you can power the printer from batteries, you must charge the 
batteries. This requires a nickel-cadmium battery charger (23-231).

INSTALLING THE BATTERIES

After you charge the batteries, follow these steps to install them.

1. Set POWER to O (off) and unplug the AC power pack's power cord.

CAUTION: Never install or remove the AC power pack while it is plugged into
a power outlet.

2. Pull down the AC power pack release so that the power pack pops out.
   Then, slide out the AC power pack.

NOTE: Store the power pack in a low-humidity, clean place where it is not 
exposed to direct sunlight.

3. Then, insert the batteries into the holder and attach the batteries' 
   connectors to the holder's connectors.

4. Slide the battery holder into the printer. Be sure it clicks into place.

LOW-BATTERY INDICATOR

When battery power becomes low, the POWER indicator rapidly flashes. When
this happens, recharge the batteries.

STANDBY FEATURE

The standby feature lets you conserve battery power by putting the printer
in the standby mode after 10 minutes of non-use. (The printer does not
enter the standby mode when you power the printer from an AC outlet).

When the printer enters the standby mode, the POWER indicator slowly
flashes. The printer automatically exits the standby mode when you print.

The STANDBY MODE function switch on the bottom of the printer determines 
whether the standby feature is on or off. STANDBY MODE is set to ON at the 
factory. If you change the STANDBY MODE setting, you must turn off the
printer and turn it back on so that the printer recognizes the new setting.
Remember to leave the printer turned off for at least 3 seconds before you
turn it back on.
