Hytera S Series Business Two-Way Radios
Another PTT in the front—enlarged size, circle shape, and phonograph-record-like texture.
135 g in weight. All for one-hand operation on the go.
Four LEDs tell you the radio status in their own way.
Talk with either of two standby groups—not just one as before.
Cover 3-5 floors and 3-5 km in urban areas; meet the indoor communication needs of more than 10,000 square meters.
With a battery life of up to 27 hours (0.5W) or 15 hours (3W) of working time and 360 hours of standby time, your focus remains on the job, not the clock.
Quickly communicate with your existing radios, regardless of brands and models.
You can clone configuration data from one S1 to many. All done in a flash.
Manage your radio with a phone, at your fingertips. Perform BT-enabled programming, batch configuration, frequency information backup, and then some.
