Charging the devices

DUT 1, 2, 3, 4 and 6 have a battery which needs to be recharged from time to time.
To recharge use the EUT 2 Charger and the charging cables provided or any 5V USB power adapter. Charging time is approx. 3-4 hours from empty to full. The status LED next to USB connector indicates charging by blinking blue and charge finished by continuous blue light.
In use, when status LED is red then battery is almost empty (<10% SOC).
Orange indicates normal operation
Green when full
LED Turns off after ~20seconds, to turn on again press the button or turn the upper part.

Antenna Gain measurement

At first, the gain of the pcb antenna needs to be measured with DUT 5. It includes the u.FL to SMA connector with 0.5dB attenuation.
Please provide peak gain and radiation patterns. We can then define the max. output power for the following measurements.

Test Setup radiated (TX)

DUT: DUT 3/4
Supply: Battery
Charging: USB
RF: Onboard PCB antenna

Devices need charging before use. After fully charged DUT 3/4 can last for 2-6 days depending on usage.

Transmit Mode

To start continuous transmission: setTxStream 1 0 0 carrier (tone) or setTxStream 1 1 0 modulated signal (PN9)

Remove USB cable for measurements after start the transmission!

To stop transmission: setTxStream 0

Receive Mode
In receive mode the DUT will listen to packets on the specified channel and print the received packet to the console.
Start receive mode: rx 1
Stop receive mode: rx 0

Communication partner for EMC Test (DUT3/4)

1. Plug the second DUT3/4 into USB
2. Open a terminal tool like Putty or hTerm with COM Port, 115200 Baud 8N1.
3. Send following commands:
   setchannel
   Start receive mode: rx 1

SAR

Please conduct the SAR measurement at the body worn distance.

FCC Band edge

For Zigbee Channel 26 and maybe Bluetooth Channel 39 it might be necessary to reduce output power to pass the band edge test. Reduce transmit power step by step until it passes the test. Inform us about used power setting or in case of any problems.

Blocking

DUT 3 or 4 as transmitter, enable CSMA for Zigbee as follows:

for Bluetooth use:

Full functional devices DUT 1 and 2

Manual control

DUT 1 and 2 are delivered in power off state. To turn them on press the upper shell down once and turn first left, then right at least one fourth turn each. When turned on, the DUT will light up with low brightness. Turn right to increase the brightness and left reduces brightness. In this state it can be controlled by PC tool deCONZ via Zigbee.

The device has following manual control modes:

• Press once will enter brightness control
• Press twice will enter the colour temperature mode
• Press three times will enter colour control mode
• Press 10 seconds to enter power off mode

Setup PC Tool for DUT1/2 control

Setup steps:

1. Install deCONZ from web https://deconz.dresden-elektronik.de/win/ newest Version as of writing: 2.16.01
2. Plug EUT 1 into USB port
3. Install USB driver (automatically by windows)
4. Run deCONZ
5. Turn on DUT (see section 7.1)
6. Activate Control panel Panels > Control
7. Open Network by Enable Permit join in Control Panel > Pairing
8. Wait until DUT shows up in main view on the right

Control DUT 1 and 2 remotely by pc Software deCONZ

To set the brightness for the DUT (screenshots below):

1. Run deCONZ

2. Select cluster info

3. Click the right dot at the DUT in main view to open the cluster list

4. Click Level Control

5. Move to Level 255 > Exec (full brightness), 0 (minimum brightness)
   To set the color of the light to a specific value, use 1.-3. And the following steps:

6. Click Color Control

7. Move to Hue: 0 for red, 85 green, 170 blue > Exec
   To set the color temperature of the light to a specific value, use 1.-3. And the following steps:

8. Click Color Control

9. Move to color temperature cold white: 153 warm white: 370 > Exec

FCC warnings

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Specific Absorption Rate (SAR) information:
This Mobile Phone meets the government’s requirements for exposure to radio waves. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons regardless of age or health.
FCC RF Exposure Information and Statement The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue.
Device types: Decolight (FCC ID: XVV-HIVE) has also been tested against this SAR limit. The highest SAR value reported under this standard during product certification for properly worn on the body is 0.150W/kg. This device was tested for typical bodyworn operations with the back of the handset kept 0mm from the body. To maintain compliance with FCC RF exposure requirements, use accessories that maintain a 0mm separation distance between the user’s body and the back of the handset. The use of belt clips, holsters and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements, and should be avoided.

Body-worn Operation

This device was tested for typical body-worn operations. To comply with RF exposure requirements, a minimum separation distance of 0mm must be maintained between the user’s body and the handset, including the antenna. Third-party belt-clips, holsters, and similar accessories used by this device should not contain any metallic components. Body-worn accessories that do not meet these requirements may not comply with RF exposure requirements and should be avoided. Use only the supplied or an approved antenna.

IC Caution
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) This device may not cause interference, and (2) This device must accept any interference, including interference that may cause undesired operation of the device.
