⏪ INSTANT REPLAY – GO BACK & HEAR IT AGAIN

The UHF040 can store up to 10 minutes of incoming audio, allowing received transmissions to be replayed when required.

This can be particularly useful for:

• 🚙 Convoy directions
• 🧭 Track instructions
• 🚛 Highway and road information
• 🏗️ Worksite instructions
• 🔊 Messages missed because of cabin or machinery noise

Instead of immediately asking another vehicle or operator to repeat themselves, you can replay the received transmission.

⭐ 3 INSTANT RECALL CHANNELS

Three Instant Recall channels provide quick access to your most frequently used UHF channels.

This can be useful for regularly switching between channels used for:

• 🚙 Convoy communications
• 🚛 Highway travel
• 🏗️ Worksite operations

---

🔍 SCANNING, DUPLEX & CTCSS

The UHF040 provides Open Scan, Instant Repeater Scan and Priority Scan, allowing the radio to monitor channel activity according to how you use it.

Duplex functionality supports compatible UHF CB repeaters, while 38 CTCSS codes can help compatible users filter unwanted received audio.

⚠️ CTCSS does not make a UHF CB channel private or encrypted. Other users can still monitor or transmit on the underlying channel.

⚠️ Duplex does not automatically increase direct radio-to-radio range. A compatible repeater must be available and within coverage.

---

⚡ 12V VEHICLE OPERATION

The UHF040 operates from a nominal 13.8V DC supply with a specified operating range of 10–15V DC, making it suitable for compatible nominal 12V vehicle electrical systems.

Built-in electrical protection includes a voltage regulator, 2A fuse and reverse-polarity protection.

⚠️ Do not connect the UHF040 directly to a nominal 24V electrical system. A suitable voltage-conversion solution would be required.

❓ FREQUENTLY ASKED QUESTIONS

What does Instant Replay do?

It allows recently received transmissions to be played back if you miss or don't clearly hear them the first time.

How much audio can the UHF040 record?

Up to approximately 10 minutes of received audio can be stored for Instant Replay.

Is it a full 5 Watt UHF?

Yes. Nominal RF output power is specified at 5 Watts.

Does it have all 80 Australian UHF CB channels?

Yes. The UHF040 supports 80 UHF CB channels, including 75 voice channels.

What are the three Instant Recall channels for?

They provide quick access to three frequently used channels without manually navigating through the full channel range.

Can I use UHF CB repeaters?

Yes. Duplex operation is supported using the standard +750kHz repeater transmit offset.

Do the 38 CTCSS codes make conversations private?

No. CTCSS can filter unwanted received audio but does not encrypt the transmission or prevent other UHF users from hearing the channel.

Can I connect an external speaker?

Yes. The radio provides a 3.5mm jack for a compatible optional external speaker.

Is the UHF040 suitable for a 24V truck?

Not directly. Its specified operating range is 10–15V DC, so a suitable 24V-to-12V conversion solution would be required.

How large is the radio?

The transceiver measures approximately 40mm high × 139mm wide × 123mm deep.

Does an antenna come with the radio?

An antenna is not identified as included in the supplied information. A compatible 50-ohm UHF CB antenna system is required for operation.
