Appendix 7A
Differentiation between 900 MHz and 850 MHz (US) version
(RH-37 vs. RH-49)
In order to serve all markets, also an US version with 850 MHz frequency support has
been implemented. There are only a few, but very important differences between these
versions.

Antenna radiator (I039) and deco foil (I041)

The antenna radiator has been adjusted for optimum performance for a particular fre-
quency. The radiator is covered with a deco foil and can be easily distinguished:
900 MHz (EU, APAC, China, LTA)
RH-37
Please note the white lines which
indicate the 900 MHz-band

RF components

Since the RF needs to be adjusted properly to the corresponding frequencies and to the
antenna, the following components are a subset of this frequency adjustment:
• C7511
• Z7700
• Z7803
