Caution
3.7 Painting the BTS cover
If desired, the BTS cover can be painted to make it better blend into the
surrounding environment.
Nokia recommends that for painting the cover a primer-topcoat combination of
Beckers TD 130 primer (for priming) and Beckers TH 141 paint (for surface
painting) be used. Other paints suitable for polycarbonate surfaces may also be
used.
Do not use any paint that contains alkalis, esters, ketones, aromatic, chlorinated,
or fluorinated hydrocarbons, since these may damage the cover. Paint containing
these chemicals can only be used if approved by the manufacturer for painting
polycarbonate objects.
The selected paint must be UV and weather-resistant and suitable for
temperatures ranging from -40 °Cto+50°C(-40 °F to 122 °F). For environmental
conditions, refer to ETS 300 019-1-4:1992 class 4.1.
To paint the BTS cover:
1. Remove the BTS cover as instructed in Nokia MetroSite GSM BTS:
Maintenance.
2. Before painting, detach the cable cover and the cable cover support from
each other to prevent them from stucking to each other by paint and to
ensure that paint is applied evenly. The cover top can also be detached from
the cover by unscrewing the Torx T20 screws (see Figure 6).
