Situation Ways to Save Battery Power Description<br />

You are operating the<br />

reader and the NiCad<br />

battery pack charge<br />

becomes low.<br />

You are using RF<br />

communications.<br />

2-42<br />

• Remove the battery pack<br />

and insert another charged<br />

battery pack.<br />

• Attach an external power<br />

supply to charge the<br />

battery pack installed in<br />

the reader.<br />

• Put the reader in Storage<br />

mode.<br />

• Use the Duty Cycle<br />

parameters.<br />

Unless the reader is in Storage mode, you need<br />

to keep a charged battery pack installed in the<br />

reader to save the lithium bridge battery’s<br />

power. For help, see “NiCad Battery Pack”<br />

earlier in this chapter.<br />

Duty Cycle automatically alternates RF<br />

communications between Receiving and<br />

Standby mode. In Standby mode, the <strong>JANUS</strong><br />

device uses less NiCad battery pack power.<br />

Using an External Power Supply<br />

You can operate the reader using an external power supply with the following<br />

<strong>JANUS</strong> <strong>2020</strong> accessories:<br />

• Communications dock<br />

• Optical link adapter connected to a power supply<br />

You can use the external power supply and charge the reader’s NiCad battery<br />

pack at the same time. For help, see the accessory quick reference guides.<br />
