Setup
1. Power Supply
The Tecsun CR-1100 DSP radio can be powered by either batteries or an external DC adapter.
- Batteries: Open the battery compartment (16) on the rear of the radio. Insert four (4) D-size batteries (not included), ensuring correct polarity.
- DC Adapter: Connect a 6V DC power adapter (not included) to the DC 6V adapter jack (17) on the rear of the radio.
2. Antenna
For optimal reception, extend the telescopic antenna (11) fully when listening to FM broadcasts. For AM reception, the radio uses a built-in ferrite bar antenna, but an external FM antenna can be connected to the external FM antenna jack (19) on the rear panel for improved FM signal.
Operating Instructions
