KAVAN M+ - User manual

Introduction

Congratulations on your purchase of the KAVAN M+, a tiny S.BUS receiver with telemetry.

It features advanced interference suppression for reliable, stable signal transmission across the entire range. Smart transmission system assignment 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 variometer 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 & Automatic binding (Smart Match )

Follow the step below to finish the Registration & binding procedure:

1. Put the transmitter/transmitter module into [Reg] status.

1.1 For Taranis X-Lite Pro as an example, turn on the transmitter, go to the MENU-MODEL SETUP-PAGE 2,choose Internal or External RF, and select [Reg].

2. Connect the battery to the receiver while holding the button on the receiver. The RED LED and GREEN LED on the receiver will be on, indicating into the [Reg] status. Select [ENTER] on the transmitter, The RED LED and GREEN LED on the receiver will flash, and the transmitter displays [Registration ok].

3. Turn off the receiver.

4. Move the cursor to select the receiver 1 [Bind].

5. Connect the battery to the receiver, the GREEN LED will flash, indicating into the [Bind] status. Select the RX, the GREEN will keep lit, and the transmitter displays [Bind successful].

6. The transmitter exit [Bind], GREEN LED will keep lit, RED LED will be off, indicating Working normally.

Note Once the receiver is registered, the button is not needed anymore in the binding process.

How to switch the F.Port

-- For Taranis X-Lite Pro as an example, select the Receiver, press the ENTER button, select the Options, and select F.Port.

About OTA function

-- For Taranis X-Lite Pro as an example, go to the SD CARD 2/7, and select the FW, press the enter button, select [Flash receiver OTA], power on the receiver, select the RX, go to the [ENTER], complete the flash process, the transmitter will display [Flash successful]. Re-power the receiver and wait for 3 seconds, the Green LED starts flashing indicates the receiver works properly at the moment.

Note Please do not do the binding operation in the near range while the firmware upgrading in progress.

Note Update the firmware after the receiver gets bound.

Range Check

A pre-flight range check should be done before each flying session. Reflections from nearby metal fences, concrete buildings or trees can cause loss of signal both during range check and during the flight. Under Range Check Mode, the RF power would be decreased and Range distance to 1/30 --1/10 that of Normal Mode.

* The signal is completely lost is recommended as the node to complete the range test.

1. Place the model at least 60cm (two feet) above non-metal contaminated ground (e.g. on a wooden bench). The receiver antenna should be in vertical position.

2. For Taranis X-Lite Pro as an example, turn on the transmitter and power on the receiver, go to: SETUP 2/13 /Internal RF/ Module [Rng].

3. For transmitter RF module, please refer to its manual.

Much more operation and instruction please refer to radio manual.

Failsafe

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 it. 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.

Note: If fail-safe is not set, the model will always operate with the last functional state of the channels before the signal loss. This could cause potential damage. If fail-safe is disabled on the RF module side, the receiver will go to the default Hold mode. Do not set the Fail-safe mode for the SBUS port to No Signal mode as the signal would be continuously transmitted, set the SBUS port to Hold or Custom mode.
