Charging Battery
The battery is built into OTR Module.
•The battery is not charged when the unit is shipped from
the factory and must be charged before using the unit.
•If the plug for the AC adapter does not fit the electrical
power receptacle, it is the user’s responsibility to find a
suitable plug adapter.
•Use only the AC adapter made for ROOT ZX II.
1. Line up the arrow on the AC adapter’s connector with the
small triangle above its jack on the side of OTR Module and
plug it in. Then plug the adapter into the electrical power
receptacle.
•Do not use the unit when the AC adapter is connected.
2. The amber Charge LED on the back of OTR Module starts
flashing on and off and then, after a few seconds, it will stop
flashing and stay on to show that the battery is being charged.
It takes about 60 minutes to fully charge the battery.
•If [F.02] appears in the display, noise has been detected.
Turn the unit off and then back on again. If [F.02] still
appears, stop using the unit and contact your local dealer
or J. MORITA OFFICE.
3. Amber Charge LED goes out when the battery is fully
charged.
4. Disconnect the AC adapter from OTR Module and unplug it.
•Never operate the unit with an external power supply.
•If an electrical storm occurs while the battery is being
charged, do not touch the AC adapter or the charger’s
power supply cord as there would be a risk of receiving an
electric shock.
•The AC adapter must be located outside the patient
environment (2.0m / 6ft. around the patient location) when
the AC adapter is connected.
•Do not pull or yank the cord when disconnecting the AC
adapter.
