Basically, if you can remote your talkback with a wire, you can install the TB-4. Typically, the TB-4 is connected to single-pole switches. If your console uses multi-pole switches for talkback, you may need to modify your console to connect the TB4 (see application notes).
How long will my battery last?
The battery supplied with the TB-4 is a premium 9v NiHm battery made by Varta. It's lifetime will vary substantially according to your use but, on average, it should last 4-5 years. After that, it will not hold the charge as well anymore, affecting your system performance. Therefore we recommend that you change it periodically.
In an emergency, can I replace my battery with any 9v battery?
Yes, in an emergency, you can insert any new 9v battery in your transmitter. But if you plan on recharging your battery, make sure it is a rechargeable one. We recommend a premium 9v NiHm 150 mA rechargeable. Regular rechargeable batteries don't hold as much charge as the premium ones and, as a result, the system performance goes down.
