On a building site many radio signals compete, and metal as well as concrete additionally attenuate the radio path. Knowing the typical sources of interference usually lets you work around them with simple means, without changing anything on the device itself.
Understanding the radio path
Between the remote and the receiver unit the radio signal must penetrate or bypass obstacles. Metal bodies, loading containers, concrete walls and even dense rows of vehicles noticeably weaken the signal. Just a few steps to the side with a clear line of sight often improve the connection considerably.
Other radio sources as interferers
Cranes, other radio remotes and data radio operate close together on a site. Brief dropouts caused by other transmitters are possible but usually disappear by themselves. If interference always occurs at the same spot, a test elsewhere helps narrow down the source.
When the device itself is the cause
If the connection stays weak even outdoors with fresh batteries and a clear view, the cause lies in the device, often in the antenna or RF section. Then choosing a different spot no longer helps. Send the remote in for a check, we test the entire radio path.
Frequently asked questions
Can phones or Wi-Fi interfere with the ISAR 3?
Strong transmitters in the immediate vicinity can interfere briefly, but lasting problems from this are rare. Persistent interference usually has another cause, such as weak batteries or a fault.
Does moving closer to the vehicle help?
Yes, shorter distance and a clear line of sight are the most effective immediate measures. Always keep a safe distance from the tipping area.
The interference only occurs with the engine running, why?
Electrical consumers on the vehicle can generate interference. If the problem is reproducible, the vehicle electrics and receiver unit should be checked together.
