This radio runs on three AA batteries or its outlet power via an AC/DC converter (not included). There are also jacks on the top to connect to an external microphone and headset (also not included). All of these jacks are sealed by rubber plugs that fit snugly enough to make this one of the few splashproof FRS radios on the market. The feel of the unit exudes quality, and except for the fragile-looking flip-up antenna, this is one radio that could easily absorb several drops onto cement and come up asking for more.
On the downside, the KX-TR320 has rather small buttons that are difficult to see, let alone press. And they're packed so close together it's easy to press the wrong one. This fault can be turned into an upside, as it's also difficult to inadvertently press a button just by handling the unit, but we found using the KX-TR320 in less than optimal lighting conditions to be a chore.
However, both the sound quality and range of the unit were excellent, and if you have two or more of the radios you can take advantage of the privacy subcodes that only let you hear people using the same subcode (although everyone else on the same channel who isn't using the codes can hear you). We've seen better overall values, but the KX-TR320's rugged construction and rich features really add to its appeal. --T. Byrl Baker
The KX-TR320B has 38 different privacy codes so you can selectively include or exclude other two-way radio users. Other Palm Link two-way radio users can monitor or join your conversations if they are operating on the same combination of channel and privacy codes. You can search all 14 channels and 38 privacy codes for active transmissions with the scan function.

KX-TR320B's rugged design with rubberized trim and grip helps absorb
the impact of the occasional knocks and bumps that come with outdoor
use. It is also splash resistant in case you get caught in the rain.
The ring-call alert lets you choose from five ringer tones, and you
can call other users by pressing the call button. It has a
multifunction backlit display, so even in complete darkness the screen
displays channel, privacy code, battery strength, key lock status,
transmit status, ring mode, and voice operation mode.
