Frequently Asked Questions

What is ANI (Automatic Number Identification) in Selcall?

ANI is an enhancement to the Selcall system where the calling radio automatically transmits its own Selcall number along with the call. When the TX4400 receives a Selcall, the caller's unique 5-digit number is decoded and displayed, allowing the operator to know who called without a voice exchange. Combined with Alpha Labelling, the caller's name (rather than just their number) can be displayed if stored in the radio's memory.

What is Page Transpond Mode?

Page Transpond Mode allows the TX4400 to automatically respond to an incoming Selcall without the operator needing to press any button. When a Selcall is received matching the radio's own number, the radio automatically transmits a brief acknowledgement signal back to the caller — confirming that the radio is active and in range. This is useful in fleet and work contexts where confirming contact without requiring a spoken response is valuable.

How are the 20 extra receive channels programmed?

The TX4400 includes 20 extra receive-only channels that can be programmed to any frequency between 465–485MHz directly from the radio's front face controls — no computer or software connection required. The operator puts the unit into Programming Mode and enters the desired frequencies. Channels can be changed or deleted at any time. This feature is available only on units with a serial number higher than 10803340.

Is the TX4400 upgradable to 80 channels?

No — the TX4400 is a 40-channel-only radio and cannot be upgraded to 80 channels. If 80-channel operation is required, the TX3500 or TX4500 series (which support 80-channel operation) would be more appropriate.

How does the DIN-sized case differ from a compact radio?

A standard DIN-sized unit (also called 1-DIN) measures approximately 50mm high × 180mm wide and is the universal in-dash slot size for car audio head units. A DIN-sized radio like the TX4400 slots directly into this opening in the dash for a clean, factory-integrated appearance — no additional mounting bracket or surface mount is required where a DIN slot is available.
