Specifications

Use and tips

The DP735 is built for places where a standard handset would not last: warehouse, loading dock, workshop, professional kitchen, clinic or care home. It withstands moisture, dust, drops and frequent cleaning with disinfectant, and its 65-hour battery life covers several days. It only works with a Grandstream DP750, DP752 or DP755 base station, sold separately; the DP755 offers maximum range and 20 SIP accounts. For office use with no need for waterproofing, the DP730 or DP725 will do.
