INSTALLATION72.8 GRYPHON™ M BATTERY MAINTENANCE2.8.1 Battery TypeYou can install NiMh, NiCd or Alkaline AA batteries in the Gryphon™ M.2.8.2 Battery ChargingOnce the system is connected and powered, you can place the Gryphon™ M into thecradle to charge the battery.When the scanner is correctly inserted in the cradle, the red LED on the cradle goes onto indicate that the battery is charging. The green LED on the cradle goes on when thebattery is completely charged.When using NiCd or NiMh batteries, frequent recharging before fully discharging cancause a “memory effect” in which the batteries assume a reduced capacity.Since it is not practical to wait for the reader to be fully discharged before recharging it,the OM-Gryphon™ and the C-Gryphon™ are provided with a battery-reconditioningfeature which overcomes the “memory effect” problem.To perform battery reconditioning, simply press the battery-reconditioning key on thecradle control panel: the battery will be fully discharged in a short period of time (redLED flashing), then automatically recharged.We recommend performing the battery reconditioning once every few months orwhenever you feel the battery capacity has decreased.2.8.3 Replacing GRYPHON™ M BatteriesTo change the batteries in your Gryphon™ M scanner, proceed as follows:1. Unscrew the battery cover screw.
