KAVAN R6L - User manual
Introduction
Congratulations on your purchase of the KAVAN R6L, a 6-channel telemetry receiver. It operates on ACCESS transmission system and has 6 high-precision PWM channels and 16 or 24-channel modes using S.BUS. Thanks to its compact size and light weight, it is especially suitable for small models and low-profile compartments, but you can use it for a variety of other models as well. With redundancy support, it can be connected as a primary receiver via S.BUS. Thanks to the F.BUS connection option, you can also pair it quickly and easily to several different telemetry devices.
It features advanced interference suppression for reliable stable signal transmission across the entire range. Smart Match system speeds up pairing. The black box function stores essential flight data. Receiver operating statuses are indicated by an LED indicator. Smart pairing allows firmware updates wirelessly.
It is also available in a Stabi version, which provides more accurate and faster measurement and transmission of altitude and vertical speed data. It also allows instant audio feedback from the variometer to the ACCESS transmitters.
If you have any questions about the R6 receiver and its operation, please contact the technical support and service staff at KAVAN Europe s.r.o. by e-mail (info@kavanrc.com for general technical information, servis@kavanrc.com for service) or by phone (+420 466 260 133 for general technical information, +420 463 358 700 for service), during business hours 8 am–4 pm, Monday–Friday).

Registration and pairing
Before you can start using your receiver, you must first register it:
- Turn on the internal module of your transmitter.
- Power on the receiver while holding the pairing button pressed. The red and green LED indicators are on, indicating the [Reg] status.
- Once RID, RX name and UID are shown, press [Register]. The red and green LED indicators are blinking.
- Power off the receiver.
After registration, commence the pairing:
- Select an empty receiver slot and press [Bind].
- Power on the receiver.
- Once the receiver is shown on the display, select it. The green LED indicator is on.
- The pairing process is confirmed by a [Bind successful] message in the transmitter.
Stabilisation functions (R6L Stabi)
Range check
A range check should be performed before each flight in case a loss of signal is caused by reflection from metal or concrete structures, and the blocking of the signal by buildings or trees during flight.
- Place the model at least 60 cm on a non-metallic support (such as a wooden bench). The receiving antenna should be in a vertical position.
- Enter the ETHOS system, go to "RF system", select the "RANGE" mode and press [ENTER]. In the range check mode, the effective range will be reduced to 1/30.
Fail-safe emergency rates
When Fail-safe is turned on, 3 modes are available: No signal, Hold, Custom.
No signal: When the signal is lost, the receiver does not send a control signal to rates on any channel. To use this mode, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
Hold: The receiver keeps the rates as they were before the signal was lost. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
Custom: The receiver keeps the rate values on all channels as you preselect them. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to "Custom". Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.
Warranty and post-warranty service
