BATTERY MANAGEMENT SHEET FOR THE ESCHMANN T20 OPERATION TABLE
CAUTION
Continued use of the table batteries in the ‘critically low’ state can damage the batteries.
Batteries within the table base are mains rechargeable, to maintain peak battery performance the table batteries should be placed
‘on charge’ at the end of each day or shift, do not wait a ‘low’ battery indication, it is good practice to charge daily. Batteries must
be charged at the end of the shift when a ‘low’ indication is given and as soon as possible when a ‘critically low’ indication is given.
Batteries should be checked for adequate charge before using the table for any surgical procedure. The orange battery LEDs on the
corded handset indicate a ‘low’ battery and the red LEDs indicate a ‘critically low battery’. When the ‘critically low’ battery warning is
indicated the table cannot be operated by either of the handsets or the footswitch. To continue to operate the table either connect it to
a suitable mains supply and recharge the batteries, or use the standby batteries or control panel. To use the standby batteries the
standby battery switch must be pressed and held depressed whilst the required motions are conducted using the normal controls.
To recharge the table batteries (normal and standby) connect the mains cord supplied (do not use any other cord) into the
mains inlet. Connect the mains cord to a suitable mains supply (check voltage) and switch the supply ‘on’ if controlled by a
switch. The battery charging LEDs will illuminate ‘red’ to indicate ‘bulk’ recharge, ‘amber’ to indicate ‘top-up’ charge and ‘green’
to indicate a fully charged battery on ‘trickle’ charge. Note: The standby control panel can be used even when the ‘critically
low’ battery indication is given but note the warning given in section 4.6.5 of the ‘Instructions for Use’.
