Q: I notice that the manual is nice and basic, any particular reason?
A: The AUSCB manual was deliberately keep simple, so people might actually attempt to read it. Type approval/compliance to Australian Standards for CB also requires specific things to be mentioned in the manual, like common channel usage, the difference between wide band radios and narrow band radios etc.
Q: What is the Moni Button?
A: The Moni button is short for Monitor Button. It is a short cut, which opens the squelch fully, to receive any receivable signals, that may have been too weak to get past the squelch gate setting. Rarely ever used, and mostly as a 'look see' so too speak. The squelch threshold is designed to mute receiver output noise in the absence of the desired radio signal.
Q: What do the bars on the lower LCD screen mean when they appear?
A: The bars across the bottom are an basic indicator. When receiving a signal, it gives an indicator of the signal strength. You may see more bars on the same receive signal if using the longer antenna (depending on the circumstances). When transmitting, it is an indicator of the battery voltage state during the transmit process.
Q: When I turned on the radio, an 8.0u showed very briefly in the LCD screen. What does this mean?
A: This is the radio's battery voltage indicator guide (in this case showing 8.0 volts). You may notice that the battery label lists 7.4V, which is referred to as Nominal Voltage and is sort of like average working voltage stated by the manufacturer. It is normal to charge up to 8V or slightly above, and once the battery drops below 7V (6.8-6.9) you will probably note that the radio will receive but transmit may be come inhibited. That is because it doesn't take much power to receive on, but transmit take a lot more power. Once the voltage drops down to 7V or below, consider recharging. If the voltage falls a bit more below that, the battery will turn itself off to protect itself. Li-ion Batteries don't need to be cycled like Ni-Cads, so you can recharge anytime.
Q: Does changing the power output occur on every channel?
A: Changing the power level is on a channel by channel basis. Turning the radio off and on will not reset the power level on that channel. When low power is set on a channel, a LO symbol will appear on the LCD screen. High power is indicated by no LO symbol being present. Adjusting the power from low to high is the same way as adjusting the radio from high to low.
Q: What does the (+) symbol in the LCD Screen mean?
A: You will note that the (+) sign is only visible on channels 22,23,61,62 and 63. This indicates that the transmit has been inhibited on these channels, which is a requirement of CB approval. You may have also noticed that a (-) sign occurs on the duplex/repeater channels (DUP). This is an indicator that the receive frequency is less than the transit frequency (which it is, by 750kHz). Conversely, the (+) sign can also mean a positive offset from the transmit frequency (but not in this case).
Q: What does TOT mean?
A: The TOT (time out timer) is mandatory for all UHF CB's as part of its compliance to Standards. The TOT will stop the radio from transmitting continually if the PTT (push to talk) is held down for too long. In the case of CB users, it is designed to reduce nuisance behavior (like the continual playing of music for instance). It is also there to protect the radio and protect resources like repeaters. As mentioned in the manual, the AUSCB's TOT is set at 60 seconds. This is within the TOT time restrictions of the Standard.
Q: I noticed CT and DCS on the LCD Screen briefly during radio boot up, what do they indicate?
A: You may have also noticed these symbols in the manual as well. These are indicators for when CTCSS and DCS are being used on a channel. The AUSCB does not have keypad access to the CTCSS/DCS function. Programming of CTCSS/DCS is only possible with software, which is unfortunately is not available to the general public as that is a requirement of Standards Approval. There are a couple of reasons why CTCSS/DCS was not made available through the keypad.
The AUSCB was designed as a powerful yet fairly simple to use radio. Only about 2% of CBer's ever use CTCSS/DCS or understand its use. We have in the past, seen way too many people accidentally activate CTCSS/DCS on CBs, not see it or understand it, and then think that their radio is broken because no one seems to talk to them.
Secondly, the AUSCB is an approved Land Mobile Service Radio, covering 450-520Mhz (which means it also has to be held to a higher technical standard than the average CB). These LMRS frequencies are generally set with CTCSS/DCS, and that is a feature that you want software set only, and not accessed via the keypad, otherwise it could render the radio useless if accidentally changed, or interfere with other operators using the same frequency but with a different tone.
Q: What level do I set VOX on?
A: Setting the VOX (voice operated switch) sensitivity is a trail and error thing, which depends on the amount of background noise, the type of mike/earpiece mike you are using, how far away it is from your mouth is from the mike, and how loud you talk in relation to the background noise. In truth, VOX is a bit of a two edge sword, and normally used under special circumstances, and not overly effective for in-car use. The VOX, when activated, works across all channels, and does not reset if you turn the radio off and back on. You will know the VOX is active (assuming an external mike piece is used) as the VOX symbol will be indicated in the LCD screen. Turning the VOX off is the same way you turn it on as per the manual.
Q: The battery doesn't seem to be charging.
A: Generally we find the problem here is that the wall adapter has been accidentally swapped with another from a different device, typically a 5V one. The AUSCB Charging Dock requires a 9VDC input, and will not work with a 5V or 12V one. Also, make sure you turn the Dock off when not in use (all night charging is fine, even though the battery will be charged in just a couple of hours).
