主要要在保函上说明，船期，航班，开船日期和目的港，特别要注目收货人的信息和联系方式，并注明：特别保函，本公司承担责任等字样，表示电放提单给你。
电放就是货主由于种种原因，如航期短，节省成本等，要求放弃正本提单，而是在船即将到港前以电子邮件、传真或电报方式，将提单副本发给收货人，收货人在目的港可以凭借提单副本和电放保函提货，这种情况下，出提单的船公司或货代都会要求放弃正本提单的货主出具保函，证明正本提单是货主自己放弃的，如果出现问题由货主自己负责，这个保函就是电放保函。

楼主问题其实涉及到performance security、performance guarantee、performance bond之间的区别。
performance guarantee为履约担保，可为保函，也可为保证金；
performance bond为履约保证金；performance security为履约保函。也就是说performance guarantee是总的，performance bond和performance security都是表现形式，都是performance guarantee。开保函的时候业主会要求哪种方式，一般保函居多。
仅供参考，望能帮助到你，呵呵！
