SENCOR SMR700BLUE is a portable twin radio station set designed for short-range voice communication. The set includes two walkie-talkies operating on 446 and 448 MHz with selectable transmission power and IP54 ingress protection. Each unit supports 16 basic channels plus 155 private CTCSS/DCS codes, a Li‑Ion 3.7 V battery (1800 mAh) with USB‑C charging and the option to use three AAA batteries as a backup power source.

Advantages

The radios offer selectable transmission power (2 W for channels 14–16 and 0.5 W for channels 1–13), automatic channel scanning, VOX hands-free operation and a dual-channel function for monitoring two channels simultaneously. IP54 protection ensures resistance to dust and splashes, while USB‑C charging and an 1800 mAh Li‑Ion battery provide flexible power options. A button lock prevents accidental changes to settings.

How to use

Charge the walkie-talkie via the USB‑C port until the battery is full or insert three AAA batteries for temporary use. Turn on the device, select the desired channel and transmission power according to range needs and local regulations, and press the push-to-talk (PTT) button to transmit. Use VOX mode for hands-free operation or enable the button lock to avoid accidental setting changes. For monitoring two channels at once, activate the dual-channel function.

Usage recommendations

For reliable communication, keep both units charged before use, use the lower transmission power (0.5 W) when operating in confined areas to conserve battery, and select higher power (2 W) only when greater range is needed and permitted. Observe local regulations for PMR frequency usage.
