Misc. on the TWINDRIVE®TD4 Standard system
This system is a TWINDRIVE system developed for leisure beds and for indoor use in private homes.
Warranty
This HOMELINE product is subject to warranty pursuant to the terms of LINAK HOMELINE Warranty Paper, available on the
LINAK website www.linak.com/warranty.
Maintenance
Clean dust and dirt on the outside of the system at appropriate intervals and inspect them for damage and breaks.
Inspect the connections, cables and plugs and check for correct functioning as well as fixing points.
The cleaners and disinfectants must not be highly alkaline or acidic
(pH value 6-8).
It is not allowed to use solvents for cleaning up.
Max. load running back and leg end motors at the same time in upward direction is 5500 N on back
motor, and 5500 N on leg end motor.
For customers in the US/Canada:
The mains cable for this product has a polarised plug (one blade is wider than the other). It will only fit in a polarised
outlet one way. If it does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician
to install a proper outlet. Do not change the plug in any way.
Description of the TWINDRIVE®TD4 Standard system
Each TWINDRIVE®TD4 Standard unit consists of 2 internal motors and a built-in control box, which makes it a very compact
unit. The mains cable is exchangeable. Only the handset must be paired.
Application of the TWINDRIVE®TD4 Standard system:
Irrespective of the load the Duty cycle: 10 % ~ max. 1 minute at continous use followed by 9 minutes pause.
Do not turn on the system if it is not mounted in a bed.
TD4 is a Bluetooth®based system, which means you can use hand controls based on Bluetooth®.
LINAK®offers a range of compatible hand controls: HC05BL, HC10BL, HB10BL and HC40BL. Alternatively, the Bed Control
App can be downloaded to use a smartphone as handset.
You can pair eight hand controls to one TD4. You can also pair both hand controls and app controls to the same TD4 Standard,
but only eight controls in total. If you pair more hand controls than the TD4 Standard can manage, the first paired hand control
will be deleted.
This user manual will give you a detailed description on how to pair your hand controls with your TD4 Standard.

Page 16 of 32
Push the TD4 Standard unit into the bed bracket
Lead the closing device in place Press the closing device in final position
Mounting instructions for the TWINDRIVE®system:
Mounting is made by pushing the TD4 unit into the bed bracket and thereafter slide the closing devices on.
It is IMPORTANT to be completely sure that the closing devices are in place before using the TD4.
Do not drive the TD4 Standard system without the closing devices mounted
The bed brackets must have a smooth surface without burs and welding blobs in the area where the TD4 Standard is
mounted.

Start-up (How to pair a Bluetooth®connection)
It is possible to pair multiple devices to the TD4 via Bluetooth®. See following instructions:
1. Pairing your control
Connect the TD4 to the mains via the mains cable. Now the TD4 will be in pairing mode for 3 minutes and the Under
Bed Light will flash to indicate this.
Take your LINAK hand control and press the two top buttons at the same time. Now the light will give a long blink
and indicate that the control and the TD4 are paired up.
Wait 20 seconds before disconnecting the TD4 from mains supply. Otherwise the pairing will not be saved in the hand
control.
If not disconnected from mains, the TD4 will stay in pairing mode and it is possible to connect more controls using
the same procedure as above. Be aware; you must wait 5 seconds after pairing control 1 until you can pair control
number 2. To get the system out of pairing mode – simply press any button on an already paired device.
When you operate the TD4 with two controls (can also be the app) you need to wait 5 seconds from operating with
control 1 until you can operate control 2.

Page 18 of 32
2. Pairing your smartphone or your tablet
Enable Bluetooth®on your smartphone/tablet. Open the Bed Control App. Connect the TD4 to the mains via the
mains cable. Now the TD4 will be in pairing mode for 3 minutes and the Under Bed Light flashes to indicate this.
The smartphone/tablet and the TD4 will automatically pair and the app display the operation page.The Bluetooth®
pairing mode will stop as soon as the phone is connected. Thus, we recommend start pairing the hand control and
thereafter the phone to avoid having to disconnect the power again.

Page 19 of 32
3. Pairing another device later
If you want to connect another control or a smartphone/tablet to the TD4 later, just disconnect the TD4, wait 1
minute and connect the TD4 to the mains to get it in pairing mode again. See instructions 1 or 2 above to find out
how to pair the device, you want. The previously paired device will not be deleted. If the maximum of devices (8)
are paired, the pairing of the first paired device will be deleted.
12
The TD4 will be in pairing mode every time the system has been out of power and connects again. To get the
system out of pairing mode – simply press any button on an already paired device.
If you wanted to pair a device, but did not make it in the 3 minutes pairing mode, please disconnect the TD4 from
the mains. After waiting 1 minute, connect the TD4 to the mains again – now the TD4 will be in pairing mode for
3 minutes.
4. Forced pairing mode
You also have the possibility to pair a new device by using the forced pairing mode. Just turn on the Under Bed
Light, disconnect from the mains, wait until the Under Bed Light turns off and reconnect the TD4 to the mains to
get it in pairing mode again. Take your hand control and press the two top buttons at the same time. Now the
light will give a long flash and indicate that the control and the TD4 are paired up.
How to unpair one TD4
1. Put the TD4 you want to keep paired into pairing mode and pair the hand control.
2. Send a command from the hand control and the pairing mode stops.
3. The connection between the other TD4 and the hand control is now deleted.

Mechanical Emergency lowering
Emergency lowering is meant for lowering the bed if a power failure occurs and the bed needs to be driven down into
horizontal position.
Disconnect the TD4 from the mains. Take the hex key on the side of the TD4. Underneath the TD4 are two gaps for
mechanical lowering – simply place the hex key in the gap, one end at a time, and turn the hex key in the direction
the arrow indicates.

3
It is important to turn the key in the direction indicated on the housing. Turning the key in the wrong direction can
wreck the inner hex and make mechanical emergency lowering impossible.
Do not use an electric screwdriver for lowering, use the enclosed hex key on the TD4.
