Caller ID and Caller ID Call Waiting (CIDCW) are becoming popular services offered all across the U.S. and now you can test the operation of these services with your buttset. Tired of poor sounding receivers? You'll like the high quality and high fidelity of the LB230's receiver, especially when using the Amplified Monitor. It has a high impedance circuit to stay completely transparent to phone and data lines in use and its' audio amplifiers make monitoring a line in use sound the same as being off-hook. You won't want to use a passive monitor buttset after you try the LB230!.

Auto-Off in all modes so you will get maximum battery life. Built in battery level meter displays the remaining life of the alkaline battery. Line current is displayed when off-hook, line voltage is displayed while in monitor mode.

If you ever need technical assistance or service for your LB230 the phone number to contact the manufacturer is preprogrammed in memory. Just push RCL 6. You will only find these features in a Lil' Buttie PRO test set.
