Data This icon contains a period. It appears on a <strong>JANUS</strong> display<br />

when data is buffered in the RF interface. The data is either being<br />

transmitted to the network controller, or received data has not<br />

been accepted by the reader’s application. When no data is being<br />

buffered in the RF interface, the Data icon is turned off. For help,<br />

see your <strong>JANUS</strong> RF documentation.<br />

Battery This icon turns on and stays on when the NiCad battery<br />

pack has approximately 15 to 45 minutes of power left. If you are<br />

using an RF <strong>JANUS</strong> device, you should replace or recharge the<br />

battery pack immediately because you will soon lose RF<br />

communications. For help, see your <strong>JANUS</strong> RF documentation.<br />

If you continue to operate the reader without replacing or<br />

recharging the battery pack, the battery pack charge becomes very<br />

low. The Battery icon stays on, the reader chirps every 5 seconds,<br />

and then turns off after 1 minute. The laser scanner and RF<br />

communications are turned off 15 seconds after the first low<br />

battery chirp.<br />

You cannot turn the reader back on until you replace the battery<br />

pack. The Battery icon disappears when you replace or recharge<br />

the NiCad battery pack.<br />

Disk Write This icon appears when you read from and write to a<br />

PC card in the PC card drive. The icon disappears once the reader<br />

is finished reading from or writing to the PC card. If you are using<br />

an SRAM card and the card’s lithium battery is low, the icon turns<br />

on and off every 2 seconds. For help on changing the card’s<br />

lithium battery, see “Replacing Lithium Batteries in an SRAM<br />

Card” in Chapter 4.<br />

Viewport This icon appears when you move the viewport out of<br />

the upper left corner of the virtual display, which is the viewport’s<br />

home position. When you move the viewport back to the home<br />

position, the icon disappears.
