unit will provide a temperature alarm. The allowed selectable temperature range

is - 8˚C to + 44˚C . In case you have made an illogical entry (e.g. you select 15˚C

as upper limit and 23˚C as lower limit), the unit will not accept your entry and will

from transmitter

N.B. It is recommended to have at least ±5˚C between the settings of upper and lower

temperature limit from the current temperature reading, otherwise the temperature

alarm can often be heard whenever the baby' s room temperature changes slightly.

2. A momentarily press of the mode button 10 will cause the LCD screen to show

the different settings in a cyclic order :

Lower temperature limit is set at 16˚C

Upper temperature limit is set at 29˚C

A screen showing the channel/digital code ; the out-of-range alert setting ; the upper

temperature limit setting or the lower temperature limit setting will automatically return

to screen showing the baby' s room temperature after 5 seconds if no further button

is pressed.

feedback. Too close a distance will create a screeching sound at the speaker 12 .

4. Once the unit receives a signal from the transmitter, the LCD will become backlighted

and LEDs in the level meter 11 will light up. The louder the baby' s voice, the more

number of LED will be lighted up. This feature is useful in case the parents prefer

position, the vibration icon

will also show up in the LCD. Once the received

baby' s voice is loud enough, the vibrator starts functioning. This feature is useful

when the parent is working under very noisy environment (e.g. Vacuum cleaning).

To save battery power, it is recommended not to use the vibrating alert frequently.

7. When the out-of-range alert function is set to On in both transmitter and receiver,

once the receiver is beyond the communication range of the transmitter for over

2 minutes, an out-of-range alarm will be heard. The LED level meter starts flashing

together with the out-of-range icon to alert the parents. Besides, the temperature

reading will show - -˚C . The alarm and icon will go off only when the receiver falls

back within the communication range of transmitter.

N.B. This alarm will also be heard in case the transmitter is switched off, or its battery

has run down, or its power is cut off, or the channel/digital code setting is different

between the transmitter and receiver, or the out-of-range alert setting is different

between transmitter and receiver.

8. Whenever the baby' s room temperature falls outside the range as preset by the

upper and lower temperature limits, an alarm will be heard. Depending on whether

the upper or lower limit is exceeded, the correspondingly icon and the current

temperature reading start flashing in the LCD.

starts flashing and an alarm will be heard, reminding the parents to charge up the

battery using the rapid charger. When the receiver is switched on and placed in

the rapid charger, the segments within the battery status indicator will flash in turn

while battery is being charged. Once charging is completed, the flashing will stop

and all three segments show steady up indicating the battery is full.

10.When only one segment is left within its battery status indicator, the transmitter

will send out a signal to the receiver. The transmitter low battery icon

flashing in the receiver' s LCD and a beep tone alarm will be heard. Once the

transmitter battery status indicator becomes totally empty, two beep tones will be

heard, urging the parent to replace with new battery for the transmitter.
