Description
The F4261D Series are Type-D single- site trunking, digital conventional and analog mode portable radios with IP67 dust-tight and waterproof protection. They come with built-in enhanced man down and lone worker emergency functions allowing for co-workers or dispatcher to receive an alert with a caller ID for any potential trouble.
800mW audio output power
The built-in BTL amplifier doubles the audio output power and the large 40mm speaker delivers loud audio to receive all calls under noisy environments. Even when using an optional speaker-microphone, the BTL amplifier output increases the audio output from the external accessory connector.
IP67 dust-tight & waterproof protection
The IC-F3261D series provides rugged protection against dust and water that is equivalent to IP67. The IC-F3261D series can withstand 1m depth of water for 30 minutes and its dust-tight construction shuts out powder dust, sand and other objects.
Built-in GPS
The built-in GPS receiver* offers a position reporting function which sends your current position information to other IDAS radios or dispatch stations at regular intervals or preprogrammed timing.
 * Available on specific versions.
Man down and lone worker functions for emergency calls
The man down function* automatically sends an emergency signal when the transceiver is left in a horizontal position for a preset period. The lone worker function also can transmit an emergency signal when the radio is not operated for a preset period. These emergency functions can be used to alert your co-workers or dispatcher to any potential trouble.
 * Available on specific versions.
