Power supply
This monitor can be powered with batteries, or by an AC adapter. Use the power source that best
suits the application.
●Using batteries
Only use alkaline batteries (use of lithium manganese batteries reduces battery operation time
substantially).
●How to insert the batteries
Turn the power switch (POWER) (4) off.
Remove the battery cover (8).
Insert six AA-size alkaline batteries.
Orient the batteries to the polarity (+/-)
marked on the battery case.
Close the battery cover.
●Battery life
Using alkaline batteries (LR6) … 7 hours*
* This is the standard value for use at an ambient temperature of 25°C (77°F). Battery life varies
according to operating environment, battery manufacturer, and battery storage conditions.
●Battery replacement
●
When the power indicator (6) blinks, replace the batteries with new ones (batteries can
still be used for some time after blinking starts).
●
Do not use any batteries other than alkaline.
●
Do not use old and new batteries together.
●
Carry spare batteries when using the monitor outdoors.
Caution
●
●When the batteries run down, replace them immediately with new batteries. If discharged
batteries are left in the monitor, they can leak and damage it. If batteries leak, take care to
avoid the fluid coming into contact with your skin and eyes, and wipe it away with a cloth.
●Using an AC adapter
Only use the AC adapter provided with the monitor.
Plug in to an electrical outlet.
Plug the AC adapter into the electrical
outlet, and then connect the DC plug to
the AC adapter connection terminal of
the monitor.
Caution
●
●Only use the AC adapter provided. Use of a different AC adapter could cause monitor
breakdown, overheating and fire.
●
●When the DC plug is connected to the monitor, the power supply from the batteries is cut
off. When the AC adapter is in use, take the batteries out of the monitor.

10
Caution
●
●Plugging a power plug into an electrical outlet of the wrong voltage can cause the monitor
to break down.
Remove the dummy inlet.
Before attaching the plug, remove
the dummy inlet that is attached for
shipping. It can be removed easily
by inserting a finger into area A and
lifting.
Attach the plug
1Align the groove on the plug with
the projection on the AC adapter,
then push with a finger on area B
until it clicks.
2Check that the plug is not
connected loosely
ZM-L304P (PAL) AC adapter

Using the monitor
When working outdoors or moving around, it is convenient to use the monitor with the soft case
provided. The stand provided can be used to hold the monitor in a fixed position for use.
●Using the soft case
1Attach flaps B and C to the Velcro at
A in the diagram to raise the hood.
The hood blocks light from the front
and sides, making the LCD easier to
see.
2Open the rear flap, at D in the dia-
gram, to reach the monitor terminals.
External devices can be connected to
the monitor while it is in the soft case.
Caution
●
●Do not perform any tasks other than camera adjustment with the case hanging around
your neck. Accidental tangling and tightening of the strap could cause strangulation.
●
●Do not leave the monitor swinging from the strap.
●
●The strap is only for use with the soft case. Do not use it for other purposes.
●Using the stand
Set the monitor, facing forward, on the stand, as shown in the diagram. Fit the stand into the
slot on the bottom of the monitor.
