General Instructions

1. Before starting the tour guide system

Ensure that a microphone or headset is connected to the transmitter and an earphone to the receiver. Check that the microphone/headset/earphone plug is properly inserted into the jack.
Ensure that disposable batteries are correctly inserted or Ni-MH rechargeable batteries are charged (+ to +, - to -) in each device. For systems with a built-in battery, check its charge level.

2. Correct startup of the tour guide system

Start by turning on the transmitter (or transmitters, if the system allows more than 1 transmitter to operate on the same channel) and selecting the desired transmission channel.
If the transmitter has a microphone sensitivity adjustment setting, check that it is not too low. This also applies to the "mute" function.
Then, turn on all receivers. The transmission channel should be set manually or via channel synchronization (if available in the model) to the same channel as the transmitter.
Check that the volume on the receivers is not too low.

⚠ Note
Most popular tour guide systems allow only 1 transmitter to operate on 1 channel. Starting 2 transmitters on the same channel will cause interference or no transmission.

3. Tour guide system power management

3.1. Disposable batteries

One battery bar on the display or a red LED on the device indicates a low battery level. At this point, replace the batteries with new ones, as the device will operate for a maximum of 1 hour.
If the batteries discharged too quickly, insert new ones and check their operating time, or you can try inserting batteries from a different manufacturer.
Low or high temperatures can affect battery life.

3.2. Rechargeable and built-in batteries

One battery bar on the display or a red LED on the device indicates a low battery level. At this point, place the device in the charger (if the device has a micro USB input – it can be charged with a USB cable).
Devices with rechargeable batteries are best charged 1 day or a few hours before planned use.
The charging time for rechargeable batteries in a dedicated charger depends on the model and the battery's discharge level. For a completely discharged battery, charging time ranges from approximately 5 hours to 12 hours for the highest capacity batteries. Leaving devices in the charger overnight does not cause overcharging or any damage to the equipment.
Remember to periodically replace worn-out rechargeable batteries with new ones. Depending on the manufacturer and capacity of the batteries, cycles (cyclic discharge and charge) can range from 500 to 1500.

⚠ Note
It is not recommended to connect more than one charger to an extension cord.

4. Transmission interference / no transmission - possible solutions

Check if the transmitter/receiver is turned on.
Check if the transmitter and receiver are on the same channel.
Check if the transmitter/receiver is not muted.
Check if 2 transmitters are not operating on the same channel.
Check transmission quality on another channel.
Check if the microphone/headphones are not damaged – test the receiver with an earphone and the transmitter with a microphone that you are sure are working correctly.
Check if the battery is not discharged – test the device with a battery/rechargeable battery that works in another device (you are sure it is not discharged).
Restart the tour guide system (turn off and on again).
