3 Remote Control Appearance
Remote control appearance features:
⚫
The operation surface adopts a belt grinding design to improve the texture.
⚫
The rear side adopts a big radian design to improve the comfort of holding.
⚫
The slope and highlighted edge surrounding the voice key makes the key distinct.
⚫
The keys are properly laid out. Keys in the upper area are rarely used, keys in the middle
area are most often used, and keys in the lower area are also often used but not as
frequent as those in the middle area.
− The middle area is the major operation area. Keys in this area use meta domes,
which make people feel comfortable when they press the keys.

Work mode
The remote control supports infrared (IR) and
Bluetooth modes.
When the remote control works in IR mode
and you press keys on the remote control, IR
key values are sent.

mode and you press keys (except those in the
study window) on the remote control,
Bluetooth key values are sent. (When you
press keys in the study window, IR key values
are sent.)
⚫
When used for the
first time, the remote
control works in IR
mode by default, and
it is not paired with
an STB through
Bluetooth.
⚫
After being paired
with an STB through
Bluetooth, the
remote control starts
to work in Bluetooth
mode.
⚫
When the remote
control works in
Bluetooth mode, you
can operate only the
paired STB using the
remote control.
⚫
Before connecting
the remote control to
a new STB, you
need to reset the
remote control.

Study
function
1. Press and hold the STUDY key for about 3
seconds. If the indicator is steady on, the
remote control enters the study state.
2. Press the sleep/wake key in the study
window on the remote control within 10
seconds. The indicator blinks.
3. Align the upper end of the STB remote
control with that of the TV remote control
within a distance of 3 centimeters. Press
and hold the sleep/wake key on the TV
remote control for about 3 seconds. If the
indicator is steady on after blinking for
three times, the study is successful.
4. Repeat steps 2 and 3 to study the volume
and TV/AV keys.
5. Press the STUDY key to save the study
result and exit the study state.
⚫
The study function is
applicable only to
the IR mode.
⚫
The Bluetooth and
IR functions are
unavailable when the
remote control is in
study state.
Sound pickup
When you press the voice key on the remote
control in Bluetooth mode, the remote control
starts to pick up sounds. When you release the
key, the remote control stops picking up
sounds.
The remote control
provides only the sound
pickup capability, but
not voice search, which
is an upper-layer service
of the STB.
Battery
monitoring
When the battery level is low, the remote
control indicator blinks to alert you, and the
remote control reports a low-battery event to
the STB. Then the STB displays a low-battery
notification.
N/A
OTA upgrade
The STB upgrades the remote control firmware
through Bluetooth. Both mandatory and
optional upgrades are supported, which can be
customized. Subscribers can cancel the
upgrade only in optional mode.
If the battery level of the
remote control is low or
the Bluetooth
connection between the
remote control and the
STB is not set up, the
remote control firmware
cannot be upgraded. The
upgrade takes about 3
minutes, during which
the system does not
respond to key pressing
and voice requests.
