2. Caution

2.1 Ensure the gopher is plugged into the correct outlet.

2.2 For best results, ensure the gopher well has been soaking with Buffer A for a minimumn of 4 hours and upto 12 hours or more before using.

3. WIFI Specifications

WIFI specifications for the Bridge are as follows

  • The brige only supports 2.4GHz bandwidth
  • The SSID (WIFI Name) must include a password
  • The WIFI cannot lead to a splash page for authentication

It is strongly recommended that the gopher’s WIFI

  • be on a dedicated router
  • not have alot of traffic on it
  • not be on a wireless repeater
4. Unpacking and Installation

The gopher will come with the following materials. Ensure all materials are complete and undamaged when received.

4.1 Unpacking the Lite

Unpack the Bridge and connect the power cable adaptor into the USB-C socket on the Bridge.

Place the bridge near the incubators where the sensor will be used.

Plug the Bridge in an appropriate power receptacle.  If the Bridge is not setup to WIFI, the red LED will display which is normal if the Bridge is new.

4.2 Charging the Sensor

Connect the Wireless Charger to an appropriate power supply using the supplied USB-C cable.  The wireless charger is required when the sensor needs to be charged or turned on.

Remove the Sensor from the Sensor Storage/Shut-off Case and place the sensor onto the Wireless Charging Docking Station ensuring you align the orientation of the logos correctly.

When the sensor is placed correctly on the Wireless Charger, you will see a green intermittent flashing light indicating that the sensor is charging.  A solid green light indicates the sensor is fully charged.
