Directions for use Maintenance and troubleshooting 51
7. Tighten screw in clockwise direction. To avoid stripping the screw threads, do not
tighten excessively.
8. Place the Handle into the charging station for a minimum of 10 seconds to enable the
battery protection circuit.
Recharge the battery
To recharge the battery, place the Handle in the Printer/Charger well with the LCD and
buttons facing you.
The 3.7V Lithium-ion battery used in the Handle, when fully charged, provides a full day of
operation without the need for recharging and yields a minimum of 300 double-ear tests.
This makes the instrument optimal for mass screening or off-site situations where there
may not be a need to print, but there is a need for continuous operation.
A fully drained battery should be recharged overnight (16 hours).
The unit will not power up if you do not enable the battery protection circuit.

REF
Caution To prevent equipment damage, charge the Handle only with the
Printer/Charger (#7117x).
• The Handle may be charged indefinitely without damage to the battery.
• Slight heating of the Handle during charging is normal.
• The battery will self-discharge gradually over a period of approximately 60
days when stored at room temperature (70°F/21°C); storage at higher
temperatures accelerates the discharge rate.
