Working area of infrared sensor Image:
4.1. Installation condition
1. Don't install outdoors; far from direct solar radiation, peg, large temperature variation; not near air condition
or pyrotoxin or rotating objects.
2. The installing surface should be solid , no vibration.
3. Installation should rotate to the different induction areas according to the actual needs.
4.2. Installation operation
There is hang hole in the back shell, with mounting bracket installed together. It's very convenient to hang
in corresponding place, or install by using magic tape to stick on the wall. Sensor head with horizontal rotation
of 60° is available, moving to the corresponding induction field according to the actual requirement.
4.3 Power supply and charging instruction and sleep function
It is available to use 3.7V lithium battery or external USB power for power supply; when connect to
external USB power, it will charge lithium battery and supply power for the host machine until fully charged.
If opened, with external USB power supply, after initialization, LED indicator light will flash per seconds;
after fully charged, the light will flash 2 times per 5 seconds. During charging, it will not move into sleep state
with low power consumption. If there are triggering and key-press, it will play normally. Without USB power
connection, the indicator light will not be on for long time. Only when playing or setting is the light on. If there is
no key-press operation or induction, it will move into sleep state with low power consumption.
Note: There is no any indicate to inform whether is full charged or not. With external USB power
(DC5V1A), lithium battery will be fully charged about 4 hours. The built-in protection circuit with full electricity
will automatically end the charging. If turn on it to charge, after initialization, when the induction probe is
inductive, the prompter is into the normal working state.
4.4 Turn on operation and audio storage location
When battery is supplying power, into sleep and low power consumption state, it will be awaken
immediately and enter into normal working status and play audio automatically when some one triggered or
pressed button. There is a certain delay time from dormant status to normal working status (external FLASH
about 1s, SD card about 1.5-2s, related with the card capacity and track). In normal working status, pressing
key or triggering, it will play audio immediately.
Audio storage location: support SD card (supporting hot plug ) or external FLASH audio, giving preference
to micro SD card, otherwise, it will choose built-in Flash by default. You'd better control MP3 audio numbers
less than 255. The total audio capacity of micro SD card should not be over 4G (max 32G capacity), because
with bigger capacity, the trigger play will have slower reaction.
Note:
1. SmartSound is with initialization time about 10-30s after power supply. During this time, it is normal without
any induction or slow induction.
2. For triggering or pressing to play, the time of voice output is related to whether there is audio muting in the
