Replacing batteries

If the symbol for empty batteries () appears, replace the used batteries by two new LR6/mignon/AA batteries. You must observe the correct battery polarity.
To replace the batteries of the accessory, proceed as follows

1. Once mounted, the electronic unit (A) can easily be pulled out of the wall mounting plate. Grab the sides of the electronic unit and pull it from the wall mounting plate.
2. Turn the electronic unit over to replace the batteries.
3. Insert two new 1.5 V LR6/mignon/AA batteries.
   Make sure that you insert them the right way around (see figure 12).
4. Place the electronic unit back into the wall mounting plate (see figure 10).
5. Pay attention to the flashing signals of the LED while inserting the batteries (see „9.3 Error codes and flashing sequences“ on page 31).
   After inserting the batteries, the accessory will perform a self-test (approx. 2 seconds). Afterwards, initialization is carried out. The LED will light up orange and green to indicate that initialization is complete.

Attention! There is a risk of explosion if the battery is not replaced correctly. Replace only with the same or equivalent type. Never recharge nonrechargeable batteries. Do not throw the batteries into a fire. Do not expose batteries to excessive heat. Do not short-circuit batteries. Doing so will present a risk of explosion.
Used batteries should not be disposed of with regular domestic waste! Instead, take them to your local battery disposal point.

Troubleshooting

Weak batteries

Provided that the voltage value permits it, the accessory will remain ready for operation even if the battery voltage is low. Depending on the particular load, it may be possible to send transmissions again repeatedly, once the batteries have been allowed a brief recovery period.
If the voltage drops too far during transmission, the empty battery symbol() and the corresponding error code will be displayed on the accessory (see “9.3 Error codes and flashing sequences” on page 30). In this case, replace the empty batteries with two new batteries (see “8 Replacing batteries” ).

Duty cycle

The wireless DHC accessories operate in the following frequency bands:

• 868,000~868,600 MHz
• 869,400~869,650 MHz

In order to safeguard the operation of all devices working in this range, it is legally required to limit the transmission time of devices. Limiting the transmission time minimizes the risk of interference.
The ‘duty cycle’ is the maximum transmission time. It is the ratio of the time that a device is actively transmitting in comparison to the measurement period (1 hour), and is expressed as a percentage of 1 hour.
If the total amount of allowed transmission time is reached, the DHC accessory will stop transmitting until the time limit is reached.
For example, when a device has a duty cycle limit of 1%, it is only allowed to transmit 36 seconds in 1 hour. After this, it will stop transmitting until the 1 hour limit is reached. DHC accessories fully comply to this limitation and use 2 frequency bands with a duty cycle of respectively 1 % and 10%.
During normal operation of the DHC accessories, this limit is not usually reached. However, it is possible that the limit is reached during start-up or during a fresh installation of asystem. In this case, the LED of the accessory lights up red. It may be non-responsive for a short period (max. 1 hour), until the time restriction for transmission has expired. After this period, it will operate normal again.

General information about radio operation

Radio transmission is performed on a non-exclusive transmission path, which means that there is a possibility of interference occurring. Interference can also be caused by switching operations, electrical motors, or defective electrical devices. The range of transmission within buildings can differ greatly from that available in the open air. Besides the transmitting power and the reception characteristics of the receiver, environmental factors such as humidity in the vicinity have an important role to play, as do on-site structural/screening conditions.
Hereby, Daikin Europe N.V. declares that the radio equipment type DHC EKRRVATR2BA is in compliance with Directive 2014/53/EU. The original declaration of conformity is available from the EKRRVATR2BA product pages. https://qr.daikin.eu/?N=EKRRVATR2BA
