Before using RUBY
®
+ for the first time, you must charge the four AAA
NiMH
(1000 mAh)
batteries. These batteries are included. A full charge
takes approximately
2 hours
. Refer to
Battery LED Descriptions
on
page 2 for battery status explanations. You can also use four AAA
disposable alkaline batteries to operate the unit.
Note:
Do not mix NiMH batteries with alkaline batteries. Replace all
batteries of the same chemistry at the same time. Do not mix new
batteries with old batteries. Replace NiMH batteries with 1000 mAh
NiMH batteries. Failure to follow this precaution can lead to battery
failure or leakage. The risk of explosion is possible if batteries are
replaced with an incorrect type. Do not use batteries that specify a
MAX Charging Current below 250 mA.
