Key Detector

Attach the optional Key Detector to your car key ring or other easily mis-
placed items and forget about ever losing them ever again. Using any of 
your telephone handsets, you can activate the Key Detector’s beeping alarm 
and quickly track down your lost keys from up to 200 yards away.

Enhanced Noise Reduction 

The Enhanced Noise Reduction feature suppresses background noise 
around the caller while simultaneously enhancing their voice so it’s easier to 
hear them if they’re calling from a noisy location.

Power Back-Up Operation (Handset)

A powerful battery back-up system keeps you connected even when the 
power goes out. Keep a charged handset in the base unit and you can still 
make and receive calls with the other cordless handsets.

Talking Caller ID

Now you can hear who’s calling from across the room without having to get 
up. Using text to-speech technology, Panasonic phones featuring Talking 
Caller ID announce caller ID information in between rings. What could be 
more convenient?

DECT 6.0 Plus Technology

DECT 6.0 PLUS takes the superb sound quality and outstanding range of 
DECT 6.0 phones to a whole new level. By increasing the frequency of error 
correction up to 80x, the transmission quality is improved and the phone’s 
range is extended. 

Intelligent Eco Mode

This feature automatically lowers the power consumption when you’re using 
the handset close to the base unit. Not only does it extend the available talk 
time, it’s good for the environment. When less power is used by the handset 
to communicate with the base unit, battery life is prolonged which results in 
less frequent charging and can result in fewer batteries in landfills.

Tone Equalizer

Everyone hears differently. To maximize clarity or accommodate hear-
ing loss, Panasonic added Tone Equalizer control to select models. This 
exclusive feature actually lets you adjust bass, mid-range or treble tones in  
a caller’s voice for maximum clarity.
