Power requirement

MODEL ONE with d ef au lt setting ap pl ie s to 50 Hz /2 20 v AC p ow er. Please m ak e sure th e AC power
is consistent with the specification marked on the label of the apparatus before using i t.

If MODEL ONE i s applied with a improper AC voltage, it may cause damage to i t and will lead to
safety and fire problem.

Position and ventilation

• In order for ventilation, please do n ot put an yt hi ng above the apparatus if it is installed on the rack,
such as the roof of the rack . Please do not put the apparatus into the inclosed rack or closet.

• Please place the apparatus on a flat, smooth and stable surface.

• To reduce th e len gh t of the inter connecting cables, please mount the appar at us as close as
possible to the other components

• The place for mounting should be dry and well-ventilated without being exposed to the sunlight.

•The apparatus should not be exposed to hig h temperature, moisture, steam, smoggy, or dusty
environment.

• To avoid damaging and the risk of electronic shock, do not pour the w at er d ir ec tl y on t he a pp ar at us

Warning：

1.Make sure th at all components in th e audio system are properly grounded. Please do n ot
use the gr ou nd in g disconnector which could destroy the polarity or grounding p lu g t ha t has
the safety performance, since it wi ll cause a dan ge ro us voltage between components and
lead to personal and property losses.

2.MODEL ONE could deliver a elegant and unforgettably within ultra high power.

Your power supply conditions ma y become as one of the factors to limit the system
performance based on your l is te ni ng ha bi ts , as well a s the quantity of speakers an d power
amplifiers th at yo u require in yo ur system requirements. You ma y consider to in st al l a
specified AC c ir cu it if it ha pp en s. Pl ea se cons ult a q ua li fi ed el ec tr ic ia n if the power i s
supplied by multiple AC circuit so as to ma ke sure all the c om po ne nt s are working in sa me ,
stable and low imp ed an ce gro un di ng condition. Unplug the MOD EL ONE during lightening
storms or when unused for long period of time.

3. U np lu g the MODEL ON E from the power socket before re mo ve i t and make sure the power i s
off.

Operating the Remote control

•Point it to the front panel o f t he MO DE L ONE When using the remote control . Make sure there are
no obstructions between the M od el One and remote control , such as furniture. The interference of
Light, fluorescent and plasma video displays may affect normal operation of the remote control.

•The effective distance of the remote control is about 5 meters, depending on the lighting conditions

•You can use the remote control toward to the MODEL ONE within 45°angle on both sides.

• The Valid range of t he remote control will be weakened wh en the MODEL ONE i s placed behind a
tinted glass.

• If i nt er mi tt en t failures happen when using the remote control, pl ea se r eplace old batteries with new
batteries.

Mount the battery
