Attach the charger to the main supply.
The LED on the charger will light orange (for approximately 0-85% charge), change to yellow during
charging (at approximately 86-100% charge) and will turn green when finished. If the battery is only partially
discharged, then the LED may start on yellow.
CAUTION
When the battery is low it should be recharged soon after use. Starting a Tempus on an
empty battery or leaving batteries in a low or empty state for prolonged periods may put the
battery into a deep-discharged state. In this state the battery LEDs will not light and the
battery will require a prolonged period on charge in order to return it to normal operation.
CAUTION
If none of the LEDs light, then the battery may have been deep-discharged. It should be left
on-charge attached to a battery charger (separate from the Tempus) for 24 hours to bring
the battery out of this state.
Note
Battery charger is rated at 100-240 V 50-60 Hz 0.9 A.
Recharging the battery takes up to 6 hours for a fully discharged battery
.
Charging to 90%
capacity takes 5 hours.
11.2 Wireless headset battery
The headset contains a rechargeable battery. The battery of the headset is not user-replaceable and does
not require user intervention. In the unlikely event that the headset’s battery becomes completely exhausted
and can no longer hold charge, a replacement headset can be purchased.
11.2.1 Charging the headset
RDT do not supply a separate charger for the headset. The charger is built into the Tempus Pro.
You must follow the repacking instructions provided by the Tempus Pro on screen. These will instruct you to
clean the headset after use and to replace it on its docking pin before shutting down.
If you do not replace the headset, then the Tempus will show an error advising that the headset should be
refitted.
Placing the headset onto the docking pin enables the Tempus Pro to recharge it. The Tempus Pro
recharges the headset for up to 9 hours (approx.) every time the headset is replaced. The charging cycle
will continue regardless if the Tempus Pro is switched on or off. Charging is started as soon as the headset
is fitted to the docking pin. The indicator light on the headset will light red for the duration of the charging
process. Once the headset is charged its LED will flash blue every 5 seconds. The indicator lights will go
off when charge cycle is complete (9 hours).
In addition, the Tempus Pro will top up the charge of the headset approximately every 97 days. This occurs
when the Tempus is switched off and lasts for up to 9 hours (approximately).
CAUTION
Always maintain a level of at least 10% in the Tempus battery. Leaving the Tempus battery
in a low charge state can risk it being depleted by the headset charging process.
CAUTION
Do not attempt to charge the headset using any other charging device. This will
automatically suspend the warranty and could be dangerous.
