Using the LCD Power Pack with an Outlet 

You should always leave a battery in the LCD Power Pack.  Once 
you are sure the battery is in the LCD power pack, then connect the 
power supply and power cord together.  

Connect the power cord to the outlet and the other end of the power 
supply to the back of the LCD power pack where it says “18 VDC 
3AMPS.”  (See Figure 2 & 3)  A green LED light will appear on the 
front top right corner of the power pack.  If the light is solid then 
the battery is fully charged.  If the light is blinking then refer to “Re-
charging the Battery” on page 22.  You can not “overcharge” the bat-
tery.  
Note:  The battery will drain if you leave the power switch ON 
when you are not using the LCD Power Pack.

Recharging the Battery 

The battery recharges in the LCD Power Pack.  All you need to do is 

plug in the power supply to the LCD Power Pack and the outlet and 

the battery will automatically start charging.  If the light is solid then 

the battery is fully charged. If the light is blinking then the battery is 

not fully charged.  The battery will charge while in use as long as the 

system is plugged into an outlet.  The battery will charge at the same 

rate whether the LCD Power Pack is ON or OFF.  You cannot over-

charge the battery. The battery has no memory so you can charge it 

at anytime.  However, the more charge cycles, the shorter the battery 

life.  Approximate charge time is 4 hours. 

Removing and inserting Battery from LCD Power Pack 

It is recommended to always keep a battery in the LCD Power Pack. 

The only reason you need to take the battery out is when you are 

changing batteries. 
To remove the battery, push down on the “RELEASE” button on the 

front top right of the LCD Power Pack.  (See Figure 1)  The battery 

should release from the LCD Power Pack so you can slide it out. 
To insert the battery, gently insert the battery, label facing up, into 

the base of the LCD Power Pack.  Make sure the battery is fully in-

serted.  You should hear a click.  (See Figure 2)
