The eSynic walkie talkies utilize rechargeable Lithium-Ion battery packs. To install, carefully remove the battery cover on the back of the unit and insert the battery pack, ensuring it clicks securely into place. Replace the cover firmly.

Charging

The walkie talkies offer two charging methods: either place the entire radio unit into the charging base, or remove the battery pack and place it directly into the charging base. Connect the USB charger to a compatible 5V power source such as a power adapter, phone charger, power bank, PC/laptop, or 5V car charger. The indicator light on the charging base will illuminate red during charging and turn green when the battery is fully charged.

Operating Instructions

Power On/Off and Volume Control

To power on the walkie talkie, rotate the rightmost knob clockwise. A voice prompt will confirm "Power On" and announce the current channel number. Continue rotating this knob to increase the volume. To decrease volume and power off the device, rotate the knob counter-clockwise.

Channel Selection

The eSynic walkie talkies feature 16 available channels. To select a channel, rotate the left knob. A voice prompt will announce the selected channel number. For successful communication, both walkie talkies must be tuned to the exact same channel.

Push-to-Talk (PTT)

To transmit your voice, press and hold the large "PTT" button located on the side of the walkie talkie. Speak clearly into the microphone. Release the button to switch back to receive mode and listen for incoming transmissions.

VOX Function (Hands-Free Communication)

The VOX (Voice Operated Exchange) function enables hands-free communication. When activated, the walkie talkie will automatically begin transmitting when it detects your voice, eliminating the need to manually press the PTT button. Please refer to the detailed user manual for specific instructions on how to activate and adjust the VOX sensitivity.

Built-in LED Flashlight

Earpiece Connection
