11. DC 12V socket
For the use of additional ITEC equipment, e.g. the CONFERENCE SET, use socket (10) for voltage supply. The
maximum current is 0.5A, a built-in safety advice switching off the device in case of overcharge.
12. Recharging the ITEC AV-BOX (Option: rechargeable battery)
simply connect the ITEC AV-BOX to the mains (110/220V) and leave the ITEC AV-BOX switched off. The power
indicator light (3) is on, the ON/OFF indicator light (2) is not. After approximately 10 hours the battery will be fully
recharged. The power indicator light will remain on! The ITEC AV-BOX can remain plugged in without causing
any damage.
Maintenance of the battery
The integrated lead battery is rechargeable and maintenance free; however, a few basic rules ought to be
heeded:
Do not store below a temperature of 5°C
Recharge after use.
Not having used the ITEC AV-BOX for months we recommend you switch it on for several hours and then
recharge it.
13. General advice
- Do not place microphones and speakers close to each other in order to avoid acoustic feedback too great
a distance, on the other hand, between microphone and speaker has an unnatural effect on the audience
(the sound, bear in mind, does not come from the person speaking) and makes speaking more diffi cult
(sonic speed, as we now know, is not all that fast). We recommend a distance between mike and speaker
of between 5 and 15 metres.
- Furthermore, make sure the speaker does not face the mike directly.
- Perfect as the loudspeaker system may be, the person speaking ought to annunciate loudly and clearly.
An audience of 10 should be able to understand him perfectly well without any technical support.
- The distance between the mouth and the microphone should be between 5 and 10 cms.
- It is advisable always to have an attendant near the loudspeaker controls, e.g. should the person
speaking suddenly come too close to the speaker with his mike the resulting feedback could be
remedied.
Advice on radio microphones
- Make sure the batteries of the radio microphone/s are in good condition
- High voltage cables, iron gates, metal roofs, etc. can cause interference
- Do not place the receiver or the microphone/s anywhere near potential interference sources (computers,
mobile phones etc.)
