Single Line-Status Indicator
Your RadioShack Single Line-Status Indicator quickly connects
to your telephone line and lets you know when your telephone
line is in use by another device, to avoid interruption of phone
conversations and fax or modem transmissions.
When a telephone device is in use on the same line as the line-
status indicator, its red lightbar lights. If there is an incoming
call, the red lightbar flashes. The lightbar turns off when the line
is free.
The line-status indicator has been tested and found to comply
with all applicable UL and FCC standards.

READ THIS BEFORE INSTALLATION
We have designed your line-status indicator to conform to fed-
eral regulations, and you can connect it to most telephone lines.
However, each device you connect to the phone line draws
power from the phone line. We refer to this power draw as the
device's ringer equivalence number , or REN. The REN is on the
bottom of your line-status indicator.
If you are using more than one phone or other device on the
line, add up all the RENS. If the total is more than five, your
phones might not ring. In rural areas, a total REN of three might
impair ringer operation. If ringer operation is impaired, discon-
nect one of the devices from the line.
INSTALLATION
Follow these steps to connect the line-status indicator to your
telephone or another telephone device.
1. Disconnect the modular telephone line cord from your tele-
phone.
2. Connect the telephone's line cord to the line-status indica-
tor's modular jack.
3. Connect the line-status indicator's modular line cord to the
telephone's modular jack.
After you connect the line-status indicator to your telephone,
you can use the supplied double sided foam tape to mount the
indicator near your phone jack.
