Hi all. I bought a demo CT 470 without all the accessaries. My question is how do you recharge the rechangeble batteries? Pop in 2 NimH in the battery compartment in the CDP using outboard DC supply or use separate charger to charge betteries outside the CDP? Thanks in advance.

Have not head either of them. Given a choice, which one should I get? Any suggestions? Thank you.
