1. Battery condition

- follow the instructions below

Measuring

Disconnect the charger from the table.
Check first the battery voltage by using a normal voltmeter, 12V DC area.
An example : the voltage is 11,8 V
Then connect the charger to the table and check again the voltage.
If the voltage is the same ( 11,8V) the battery is not in contact with the charger .

If the voltage now increases clearly over 11,8V it shows that charging works.
If after overnight charging the battery do not work properly it is damaged and must be
replaced.

the battery and the charger voltage:

NOTE! Check the voltage not before than one hour after disconnecting the charger

that the battery voltage first normalizes and measuring result is accurate .
The normal voltage in full battery is 12,5 to 12,7 volts.
The measuring result under 12 volts indicates that service life of the battery is
ending.

Checking the battery condition:

Using a multimeter, measure the battery terminal voltage in the table outlet box between
number one and ground terminals.

1 = battery positive (+)
terminal
Ground = battery (-) negative
terminal

Lookcarefully,
small signs.

A reading of 12.7 V or over means that the battery is fully charged.
A reading of 11 V indicates the need for immediate charging. The red indicator light at the

back of the table should be glowing.
A reading of under 7 V means that the battery is almost empty. In this case, even the red

indicator light at the back of the table does not have enough power to glow.
A reading of 0 - 4 volts means that the battery is empty. In this case, the automatic charger

is no longer able to recharge because it needs a minimum of 4 volts to function.
