15. Charger Unit

The charger unit has a 3 coloured LED ( yellow, orange and green ) that flashes 6 different
modes (see printing on charger).
When the Tonometer is first plugged into the battery charger, the battery charger LED will
show orange for several seconds while it gives a short charge to the Tonometer battery.
The battery charger will then switch to yellow for several seconds while it carries out
initialization analysis of the Tonometer battery. If the Tonometer battery condition is ok the
battery charger LED will switch to orange again for the "fast" charge and stay orange until
Tonometer battery is almost fully charged (up to 3 hours).
When the battery charger detects the Tonometer battery is almost fully charged the battery
charger LED switches to green with short flashes of yellow (up to 1 hour) to complete the
charge.
When the top-off charge is complete, the battery charger LED will switch to solid green
(trickle charge) indicating the Tonometer battery is fully charged.
Please Note:
If after the analysis mode the LED alternately flashes between orange and green, this
